The heat on certain July afternoons was almost physical, like walking into a wall. The streets between the tall buildings formed corridors that trapped it. The asphalt radiated it upward. The buildings reflected it sideways.

There was no escape that didn’t involve an air conditioner, and every air conditioner running made it worse for everyone outside. Living in Upper Manhattan, seeing kids running in the streets where they’d opened fire hydrants for some relief from the heat was a common sight.  Even with some 18,000 trees in Central Park and another 39,000+ trees mapped throughout Manhattan, NYC is still known as a top urban hot spot.

What I didn’t appreciate then was how much worse it’s supposed to get. By 2100, cities worldwide could be as much as 4.4 degrees Celsius hotter than they are today, according to climate modeling. While I wish this were a future in some other world of the Multiverse, unfortunately, it’s a countdown already underway, playing out in hospital admissions, energy bills, and the quiet daily suffering of people who can’t afford to escape.

Here’s the uncomfortable flip side: we already know the fix, and it grows out of the ground.

The case for the urban tree

A single healthy person is a performing asset; we simply haven’t been accounting for it that way. Research by the USDA Forest Service found that urban trees in Modesto, California, returned $1.89 in measurable benefits for every $1 invested in their management, through reduced air pollution, energy savings, and increased property values.

Peer-reviewed research published in Urban Science found that urban trees sequester between 10 and 20 kg of CO₂ per year, with larger trees capturing significantly more. Nearby commercial areas have been shown to see retail activity rise by 16–18%, and properties on tree-lined streets command 3–10% higher valuations, according to McPherson et al. in Urban Forestry & Urban Greening.

When it comes to the heat island problem, a 2023 study published in Urban Forestry & Urban Greening found that full tree canopy cover reduced human heat stress by a mean 5.5°C, rising to 8.8°C during extreme heat events when air temperatures reached 40°C. Trees don’t just cool cities. They make them survivable.

That’s the reframe I want to offer: trees are not amenities. They are load-bearing components of urban systems, as functional as a stormwater pipe or an electrical conduit. When we treat them as ornamental — nice to have, first to cut in a budget — we are making an accounting error with compounding consequences.

The infrastructure failure hiding in plain sight

So why don’t more cities have more trees? Part of the answer is policy and funding. But a large part is physical. Urban streets are biologically hostile environments for trees. Research across the US, UK, and Canada documents high mortality rates — with newly planted trees especially vulnerable during the first five years. A comprehensive literature review by Hilbert et al. found annual mortality rates reaching as high as 68.5% in some newly planted cohorts. Perhaps most striking: many street trees live only 20 years or less, a fraction of their natural lifespan, because the compacted, sealed, utility-dense ground beneath city pavements starves root systems of the soil volume, oxygen, and water they need to survive.

This is the infrastructure failure hiding in plain sight. Cities are not just losing trees; they’re running a replacement treadmill, replanting in the same inhospitable conditions, spending public funds over and over for an outcome that compounds their problems. Every tree that dies young takes its ecosystem services with it: years of CO₂ capture, commercial vitality, and heat mitigation that only a mature canopy can deliver.

The investable premise

This is where the nature-as-infrastructure framing stops being philosophical and becomes financial.

If trees are infrastructure, then the systems that enable them to survive and thrive are infrastructure technology. And right now, that category is nascent, under-capitalized, and about to be turbocharged by legally binding planting mandates.

I recently spoke with the founders of TreeTube. This Israeli company has been quietly building exactly this: a patented, below-ground system that creates the conditions trees need to survive in urban environments. Made from high-density polyethylene with 25% recycled materials, TreeTube installs beneath paved surfaces and provides root systems with adequate soil volume, aeration, and water access, giving each tree its own underground life-support module. It supports heavy traffic loads above ground while protecting surrounding utilities from root damage below.

The concept sounds simple, but the execution is not. TreeTube holds patents across the US, EU, Australia, Japan, Israel, China, and more. It has been approved by utilities companies and municipalities in Israel, the Netherlands, and Estonia, and has completed dozens of projects worldwide, including alongside Tel Aviv’s light rail corridor.

What struck me most in talking with them was how naturally the product fits the infrastructure metaphor. You’re not installing a plant. You’re installing a system — modular, customizable, engineered — that happens to grow something alive inside it.

The regulatory tailwind

Investable ideas need catalysts, and this one has two.

The European Union passed Regulation 2024/1991 on nature restoration in July 2024. Starting January 1, 2031, EU member states are legally required to achieve a measurable increase in urban tree canopy cover every six years. Beyond being a goal or guideline, this is a compliance obligation with a hard timeline.

These mandates transform a discretionary purchase into a procurement requirement. Municipalities don’t need to be persuaded that trees are good; they need systems that actually work in the ground conditions they have.

The investor mismatch — and the opportunity

Here’s the honest challenge: companies like TreeTube don’t fit neatly into most VC frameworks. The returns are long-term and linked to municipal procurement cycles rather than software-style growth curves. The buyers are cities. The product solves a public goods problem. Traditional investors often see this and move on.

But impact investors should see something different. The asset here is a mandated, recurring infrastructure need, backed by regulatory law, aligned with multiple UN Sustainable Development Goals, and supported by technology with strong IP protection and real-world proof points.

What the urban tree economy needs is patient capital that understands infrastructure timelines — the kind that built water networks and electrical grids over decades, not quarters. What it offers in return is something rare in impact investing: a product that is simultaneously climate-critical, commercially validated, and legally locked in.

I left that call thinking about my Manhattan summers differently. The trees were there, just stunted and doing their best in four inches of compacted soil. Nobody had built the ground beneath them to last. That’s still true in most cities, but it doesn’t have to be.

That tension became unmistakable during the recent EcoHealth dialogue convened by The Galien Foundation. The gathering brought together innovators addressing climate and environment needs, not-for-profit organizations mobilizing global youth action and corporate-enabling technologies strengthening responsible business.

Their work spans ocean-wave power, grassroots environmental leadership, women-led solar entrepreneurship, next-generation water treatment, industrial cooling, soil restoration platforms and algae mitigation technologies. Their perspectives may differ, but their commitment to science is united. However, each voiced the same underlying truth: climate tech, like medicine, advances only when society answers the defining question of our era –Who pays?

A Planet Under Stress and a Market Slow to Respond

Climate instability is not a distant worry; it is a daily force shaping people and planetary health. When lakes collapse due to toxic blooms, communities lose access to drinking water, fisheries and tourism. When drought tightens its grip, agricultural regions face diminished yields and economic pressure. When wildfire smoke drifts across borders, respiratory health deteriorates even hundreds of miles away. Stability in water, air and soil is inseparable from human wellbeing, and climate innovators working in these areas, such as BlueGreen Water Technologies, which restores threatened lakes, operate on the very front line of prevention.

Yet companies like BlueGreen often face a steep path to investment because their work benefits everyone but belongs to no single customer. A restored lake sustains tourism, agriculture, local economies, ecological health and community wellbeing. However, responsibility is spread across municipalities, counties, state agencies, and the Federal government and national ministries, all of which manage immediate crises that overshadow the slow, devastating progression of environmental decline.

The same challenge confronts innovators such as Solar Sister, which expands access to clean, safe solar energy for communities without reliable power, and the POP Movement, which mobilizes youth populations to drive local environmental action. Their impact is generational, and their value is immeasurable, yet their funding often relies on philanthropy or public grants, mechanisms that rarely match the scale of the problems they address.

Even climate technologies designed for industrial operations face the challenge of being essential but not urgent in public budgets. Infinite Cooling, for example, captures water evaporating from power-plant cooling towers, reclaiming resources that would otherwise be lost to the atmosphere. It offers a response to the costs of water as an essential business resource. Yet, because these benefits impact industries – from pharmaceutical companies to power plants – rather than county governments, adoption is championed by supply chain and corporate financial stewards. 

A similar story emerges from companies like Greenore, which is building biological solutions to regenerate soil systems. Healthy soil underpins food security, agricultural productivity and community resilience. It is as essential to global health as any medicine. However, soil restoration often lacks a corporate customer and competes with established agricultural practices and stretched public budgets.

Corporate Imperative: Climate Tech Cannot Wait

Compare these funding obstacles with the experiences of corporate-oriented climate tech innovators whose solutions support operations, reduce costs, or address regulatory pressures. Eco Wave Power illustrates the point with clarity. Its technology harnesses ocean waves to produce clean electricity, transforming coastal infrastructure into renewable-energy assets. For ports, industrial campuses, and commercial centers along coastlines, this is not only an environmental benefit but also an energy security strategy and an additional revenue source.  The value is concrete, the payer is clear. Operations leaders can place it within a capital plan.

The contrast is evident in how global companies behave. Cloud providers racing to meet AI demand are committing billions to renewable power purchases, as their data centers cannot operate without stable, cost-controlled energy. Manufacturing companies often sign long-term agreements for clean electricity because energy risk poses a significant threat to their production output and profitability. Logistics and e-commerce giants invest heavily in biodegradable packaging because regulations are tightening, and sustainable materials avoid reputational damage and secure supply chains. These forms of climate innovation do not wait for budget approvals across 10 public agencies. They fit within the clearly defined corporate operating model.

Two Speeds, One Planet

The result is a two-speed climate economy. The technologies that support business continuity scale quickly; in contrast, the technologies that protect the environmental foundations of life struggle to secure investment despite their importance.

The Galien Foundation EcoHealth dialogue highlighted the precarious nature of this imbalance. BlueGreen restores waterways before they collapse. Solar Sister brings clean energy into homes before households turn to harmful alternatives. Greenore regenerates soil before agricultural regions face collapse. POP Movement ensures communities are engaged before consequences become irreversible. However, without clear lines of accountability, these organizations perpetuate the existential paradox of the Myth of Sisyphus, who is constantly pushing the rock uphill only to see it roll down again and again.  The problem is real.  The solution is proven. The funding environment is challenging.

Meanwhile, corporate-oriented climate tech companies are racing to meet demand because their value proposition directly connects to corporate cost, efficiency, or continuity. Eco Wave Power and Infinite Cooling demonstrate how quickly solutions advance when they operate within a budget line rather than under a public-funding process.

The Answer That Determines the Future

The question, then, is not whether climate innovation exists; rather, it is whether it is effective. It is without question. The polemic is whether society is prepared to fund climate innovations that protect human survival with the same urgency as those that safeguard business operations.

Municipalities, counties, and state agencies are tasked with safeguarding water, soil and air; yet, public funding cycles often prioritize immediate crises over slow-burning threats. Tourism boards rely on restored lakes and healthy ecosystems, yet rarely have the budget authority to invest early. Agricultural departments rely on resilient soil, yet their funding models prioritize short-term yields over long-term regeneration. Responsibility is diffused across institutions, so that no one bears the full responsibility to allocate resources.

This is where climate tech faces its greatest challenge and where corporate and public leadership must step forward. Preventive climate action needs its equivalent to the payer system that supports access to health care. Blended finance, climate resilience bonds, public–private partnerships and impact investment models can help fill the gap. Policy can make restoration and resilience non-negotiable long before crises mature. Communication can transform the invisible and delayed into the immediate and owned.

The innovators showcased in the Galien Foundation EcoHealth dialogue offer a roadmap. Their work illustrates that climate technologies are not abstract “science fiction” climate solutions; they are the infrastructure of human continuity. They restore the systems that allow communities to thrive, and they ensure the global economy has the stable environmental foundations it requires.

The future of climate tech equity will be defined by whether society chooses to treat environmental health with the same seriousness as business operational resilience. Without an answer to who pays, one side of the climate tech industry will continue sprinting while the other waits for the world to catch up.

By Gaea Cabico, a freelance reporter in New York.

On the night Superstorm Sandy hit New York in October 2012, seawater from the Atlantic Ocean surged into the emergency room of what was then known as Coney Island Hospital. Staff scrambled to evacuate 28 patients to higher floors, wading through knee-deep water and holding flashlights to navigate dark hallways.

“The damage was extensive. The hospital was fully evacuated. We lost all power in the campus. It was multiple months before [the hospital] can be utilized again,” Svetlana Lipyanskaya, CEO of NYC Health + Hospitals/South Brooklyn Health, said in an interview. (Lipyanskaya, who was not at Coney Island Hospital in 2012, worked at Weill Cornell at the time.)

Today, the site, now called South Brooklyn Health, is fortified by a four-foot flood wall. A new hospital building, named after the late Supreme Court Justice Ruth Bader Ginsburg, features hurricane-resistant glass, and power and water systems designed to withstand future storms that could have once crippled the facility.

As climate change accelerates, South Brooklyn Health’s transformation reflects a growing recognition of the vulnerability of health care facilities to extreme weather events and the need for resilient infrastructure to maintain essential services. Michele Baker, policy coordinator of The Global Climate and Health Alliance, said many health facilities “were not built with these kinds of weather events in mind.”

“We learned what our vulnerabilities are,” Lipyanskaya said. “And so when we rebuilt, we rebuilt with that in mind.”

Crucial services moved to higher floors

In May 2023, the $923 million Ruth Bader Ginsburg Hospital opened, offering services to nearly 875,000 residents of South Brooklyn and nearby neighborhoods, many of whom are immigrants and low-income individuals. The Federal Emergency Management Agency funded the construction of the new hospital.

One of the key features of the hospital is its emergency department located on the second floor to ensure continuity of care during floods.

“Our new building is built so that, post-event, we could be up and running very quickly because there’s literally nothing of any key importance on the first floor,” Lipyanskaya said. The hospital’s first floor houses just the lobby and a seven-foot bronze statue of Ginsburg.

Clinical services, along with power, heating, cooling, and water systems are located on higher floors. Aside from the flood wall surrounding the hospital campus, flood barriers are installed within the building. A wind-resistant envelope further protects the structure against severe storms. During Sandy, seawater from the Atlantic, just a mile away from the hospital, easily breached the facility, even over sandbags. Violent winds blew open the windows.

In addition to infrastructure upgrades, South Brooklyn Health has also trained staff to respond to disaster situations, and the hospital has implemented a robust supply chain system to ensure uninterrupted patient care during emergencies.

“We have backups of everything, and we’re able to replenish very quickly and move forward very quickly,” Lipyanskaya said, adding that the supply chain efficiencies were more a result of the Covid-19 pandemic than Sandy.

South Brooklyn Health is not alone in bolstering its defenses against climate impacts in the city. With a grant from FEMA, NYC Health + Hospitals Bellevue, Metropolitan and Coler, which were also devastated by Sandy, have installed flood walls to protect against storm surge, elevated electrical equipment and alarm systems, and put in place backup generators to ensure operations can continue for at least 72 hours during a power outage.

Atlanta hospital flooded during extreme cold

Many hospitals across the United States remain ill-equipped to withstand the increasing severity and frequency of climate-related disasters.

About 515 hospitals in North America could face high risk of a total or partial shutdown due to extreme weather events if global emissions continue to rise at a rapid pace, according to a December 2023 report by climate-risk data analysis company XDI. Large corporations, financial institutions, insurance companies, real estate developers, and governments rely on XDI’s data to assess the climate risks faced by their properties, infrastructure, and operations.

By 2100, Florida is expected to have the highest number of hospitals at high risk under a high emissions scenario, followed by Louisiana, California, Texas, and New York, according to the report.

Last year, Hurricanes Helene and Milton paralyzed health care facilities in Florida, Georgia, Tennessee, and other Southern states, and led to shortages of IV solutions.

In 2022, Grady Memorial Hospital, a public hospital that primarily serves low-income patients in Atlanta, was crippled after an HVAC system failure triggered by extreme cold led to widespread flooding. Dr. Jamaji Nwanaji-Enwerem, an emergency medicine physician, recalled how it damaged the burn unit and knocked out several CT scanners.

“These cascading failures revealed how aging infrastructure in safety-net hospitals, which already face financial and operational challenges, is especially vulnerable to climate-related events,” Nwanaji-Enwerem said.

Safety-net hospitals may lack funding for climate-proofing

While FEMA grants provide critical funding for disaster resilience, other programs often rely on tax-related incentives, such as credits, which require upfront capital investments, said Winslow Dresser, associate director of regional climate solutions at Health Care Without Harm, a nonprofit advocating for sustainable health care practices. Wealthier institutions with strong credit ratings and better access to capital are more likely to benefit from these programs, Dresser said.

“Many safety-net hospitals lack the financial flexibility to make these changes alone,” Nwanaji-Enwerem said. “Broader federal, regional, and state policies are needed to provide funding, technical support, and incentives for climate-resilient upgrades.”

Nwanaji-Enwerem added that strengthening partnerships with local governments and community organizations can also improve hospitals’ readiness and response.

For some hospitals, bolstering defenses against climate disasters can be especially challenging if they have not experienced a major storm or wildfire. In those cases, Dresser said, the hospital leader “does not have those kinds of risks top of mind.”

While South Brooklyn Health’s infrastructure upgrades were designed to ride out the challenges of a changing climate, its CEO stressed that resilience is about more than just disaster-proof buildings.

“We really need to focus on providing care to patients where they are and think much more broadly about what happens outside the walls of the hospitals,” Lipyanskaya said, adding the improvements have also allowed the hospital to expand its services to better support the surrounding community.

For a few rare hours, COP30 wasn’t just about parts-per-million or political posturing. It was about bodies, systems, and communities under strain, and what the world intends to do about it. That shift in tone was unmistakable, and long overdue, as Health Day finally put people — not just policies — at the centre of the climate story.

Climate-Sensitive Diseases on the Rise

Climate change is intensifying the spread and severity of infectious diseases that thrive in warmer, wetter environments. Delegates at COP30 highlighted how shifting rainfall patterns and rising temperatures are expanding the range of vector-borne diseases, such as malaria and dengue fever. “Rainfall patterns are less regular, facilitating the spread of mosquito-borne diseases such as malaria and dengue,” reports Doctors Without Borders (MSF), which notes these illnesses can become deadlier when combined with malnutrition.

In 2024, the Americas experienced their largest dengue outbreak in history – a sign of how a warming climate is amplifying epidemics. Meanwhile, extreme heat is emerging as a major killer: heat-related deaths have surged 23% since the 1990s, now exceeding half a million per year. Health officials warn that without more decisive climate action, diseases like cholera, Zika, and yellow fever could similarly gain ground, placing millions more at risk in the coming decades.

A mother tends to her child suffering from malnutrition and malaria at an MSF clinic in Madagascar. Climate change exacerbates nutrition and disease crises – droughts, crop failures, and flooding drive malnutrition, which in turn makes infections like malaria or dengue more deadly.

Beyond tropical diseases, extreme weather events linked to climate change are causing direct injury and indirect health crises. For example, successive floods and landslides in Brazil’s Rio Grande do Sul state in 2023–2024 killed thousands and displaced hundreds of thousands. MSF teams on the ground provided mobile clinics and mental health support, treating injuries and waterborne disease outbreaks in overwhelmed communities. Each disaster weakens local health systems and increases vulnerability to the next. “We are not talking anymore about distant or possible threats,” noted Dr Jarbas Barbosa, Director of the Pan American Health Organization (PAHO). He pointed out that the Americas just experienced its hottest year on record, with cascading health impacts: in 2024 alone, 154,000 people in the region died from exposure to wildfire smoke. Such statistics underscore that climate-sensitive health risks are no longer hypothetical – they are happening here and now, and they disproportionately strike vulnerable populations with the least resources to cope.

Air Pollution: A Dual Climate and Health Crisis

Air pollution emerged as a prominent concern at COP30, given its tight links to both climate change and public health. The burning of fossil fuels – the chief driver of global warming – also poisons the air, causing an estimated 7–8 million premature deaths each year from respiratory and cardiovascular diseases. This makes air pollution “the climate crisis already inside our lungs,” as advocates framed it. Cleaner air is a clear example of the co-benefits of climate and health. Every measure to reduce greenhouse gas emissions (such as phasing out coal and oil) also reduces particulate pollution, yielding immediate health benefits. “Cleaner air, safer water, sustainable food systems, and resilient infrastructure mean healthier communities and better lives – a triple win for human health, the economy, and the climate,” noted UN Climate Chief Simon Stiell. Policymakers at COP30 stressed that decarbonising energy and transport systems could prevent millions of deaths from air pollution while also slowing climate change.

Despite this, there was debate about how explicitly the COP30 process should link the phase-out of fossil fuels with health outcomes. A major climate-health plan launched in Belém notably omitted any reference to fossil fuels, reportedly at the host country’s instruction. Health experts warned that ignoring the root cause of both global warming and toxic air would be a mistake: “8 million people are dying annually from air pollution, yet the plan didn’t mention phasing out fossil fuels,” one observer noted. The omission comes as the International Energy Agency warns that oil and gas demand could continue rising for decades unless stronger policies are implemented.

Many countries still heavily subsidise fossil fuels – in fact, 15 nations spent more on net fossil subsidies than on their entire health budgets last year. In side events, organisations like the Global Climate and Health Alliance urged governments to commit to a just transition away from fossil fuels, framing it as a public health imperative. They emphasised that bold mitigation action – shifting to clean energy and transport – is needed not only to meet climate goals but to reduce the enormous health burden of air pollution.

Mental Health: The Invisible Toll of Climate Change

COP30 brought unprecedented attention to the mental health impacts of climate change. As climate-related disasters multiply, communities face not just physical harm but profound psychological stress. “Repeated and overlapping extreme events…erode psychological and emotional resilience, causing complex trauma,” MSF observed in a statement. In flood-ravaged areas of Brazil, for instance, families suffered the trauma of displacement, loss of loved ones, and the anxiety of rebuilding in an uncertain future.

MSF responded by training local professionals in psychological first aid and providing mental health support in emergency shelters. Such stories highlight what experts call “climate distress” – the depression, anxiety, and hopelessness that can follow climate disasters or even the anticipation of climate change. Youth delegates at COP30 spoke out about climate anxiety, noting that the fear of an unstable future is affecting the mental well-being of young people worldwide.

For the first time in COP history, mental health featured centrally in an official climate-health framework. The newly launched Belém Health Action Plan includes a comprehensive section on integrating mental health into climate adaptation. It urges concrete steps, such as embedding mental health and psychosocial support (MHPSS) in national climate-health plans, strengthening mental health services to withstand disasters, and providing community trauma support after extreme events. “Resilient communities are also mentally healthy communities,” advocates stressed, calling mental health an essential component of climate resilience. Negotiators in Belém acknowledged that addressing psychological recovery and well-being is critical to a comprehensive climate adaptation.

There were calls to track mental health outcomes under the Global Goal on Adaptation, using new indicators (such as the proportion of communities with MHPSS programs for climate emergencies) to ensure countries report progress. This represents a significant shift – from historically sidelining mental health in climate talks to recognising it as a pillar of the response. As one Brazilian official put it, “If our efforts overlook local and Indigenous knowledge, we risk ignoring real needs and deepening existing inequalities”, – and mental health needs are part of those fundamental needs. By the close of COP30’s Health Day, countries were encouraged not only to cut emissions but also to invest in healing the invisible scars that climate change leaves on minds and communities.

Nutrition and Food Systems Under Strain

Climate change is undermining food security and nutrition, a point that has been repeatedly underscored at COP30. Droughts, floods, and shifting weather patterns are disrupting agriculture and worsening hunger in many regions. As crops fail or yields decline, communities face higher rates of malnutrition, which in turn exacerbates health vulnerabilities.

“In Zimbabwe, drought resulted in crop failures,” MSF reported, “which drove farmers to informal mining…then access to safe water became a major issue” requiring emergency intervention. In the Sahel and Horn of Africa, prolonged droughts have pushed millions into a food crisis, illustrating how climate change can trigger a vicious cycle of famine and disease. Malnutrition weakens immune systems and makes infections more deadly; MSF noted that diseases like malaria became more lethal amid malnutrition spikes in Nigeria. Conversely, climate-fueled disease outbreaks (such as diarrheal illnesses or cholera after floods) can worsen malnutrition by causing nutrient loss.

At COP30, experts highlighted the resilience of food systems as a priority for both mitigation and adaptation. Sustainable, climate-smart agriculture was promoted to both reduce emissions and ensure reliable food supplies. Representatives from vulnerable countries emphasised that erratic seasons and extreme weather are already crippling farmers and driving up food prices, with the poorest communities being hit the hardest.

The World Health Organization has warned that climate change is a “risk multiplier,” exacerbating food insecurity, which in turn leads to undernutrition and stunted growth. Indeed, the COP30 special health report found that 3.3 to 3.6 billion people already live in areas highly vulnerable to climate impacts – many of these are subsistence farming communities facing heightened risks of hunger. In policy discussions, there has been a push to incorporate nutrition into climate adaptation plans, for example, by developing early warning systems for crop failures and integrating nutrition programs into disaster response efforts.

Delegates noted that every climate adaptation measure – from drought-resistant crops to flood-proof infrastructure – ultimately has a human face: “These are not statistics – they are families, communities, and futures already paying the price of global heating,” said Simon Stiell, emphasising that food security and health security go hand in hand. By the end of the summit, calls for “sustainable food systems” were woven into the broader narrative that climate action must protect the foundations of health, including the availability of nutritious food and clean water.

Building Climate-Resilient Health Systems

A clear theme at COP30 was that health systems themselves must be fortified against climate change. Hospitals and clinics on the front lines are increasingly overwhelmed by climate shocks – from cyclone damage to heatwaves flooding emergency rooms – and many lack the capacity to respond effectively. The WHO warned in a new report that “over 540,000 people [are] dying from extreme heat each year and 1 in 12 hospitals worldwide [is] at risk of climate-related shutdowns” as of 2025. By mid-century, the number of health facilities at risk could double unless we bolster infrastructure to withstand floods, storms, and heat. Already, hospitals face a 41% higher risk of damage from extreme weather compared to 1990. These stark figures underscore the urgency of investing in climate-resilient health systems, enabling clinics to withstand disasters and continue providing care when it’s most needed.

MSF teams navigate a landslide in Mexico to reach remote communities after intense rains. Climate-related disasters are striking vulnerable areas with increasing frequency, underscoring the need for resilient infrastructure and rapid health responses.

At the COP30 Health Day, Brazil, as the host nation, unveiled the Belém Health Action Plan, a comprehensive framework to strengthen global health sector adaptation. “For decades, WHO has been calling for action to adapt health systems… The Belém Health Action Plan is how we can do that,” said Dr Tedros Adhanom Ghebreyesus, WHO’s Director-General. The plan lays out over 60 recommended actions across three pillars: (1) climate-informed surveillance and early warning, to predict outbreaks and extreme events; (2) evidence-based policies and capacity-building, to protect communities through measures like heat-health alert systems, clean energy in hospitals, and mental health support; and (3) innovation and green technologies, from telemedicine to climate-resilient medical supply chains.

These strategies align with the plan’s cross-cutting focus on health equity and climate justice – recognising that poor and marginalised groups are most at risk. “The climate crisis is one of the most significant health challenges of our time,” the plan declares, warning that rising temperatures and collapsing health systems will claim ever more lives without urgent intervention.

Real-world examples illustrate the scope of climate-resilient health measures. PAHO expanded its “Smart Hospitals” initiative, which has retrofitted over 70 Caribbean hospitals with disaster-proofing and solar power. Those upgrades paid off when Hurricane Melissa struck recently – the smart hospitals in Jamaica stayed operational and saved lives, even as other infrastructure failed. Similarly, early warning systems are scaling up: between 2015 and 2023, the number of countries with Multi-Hazard Early Warning Systems doubled to 101, covering approximately two-thirds of the global population.

However, many low-income nations still lack these capabilities (only ~46% of Least Developed Countries have an effective warning system). Critical gaps remain: fewer than half of national health adaptation plans assess climate risks to health facilities, and fewer than 30% consider the impacts on vulnerable groups, such as people with low incomes or women. Health workforce training is another gap – most countries need more climate-trained health personnel and emergency planners.

“Many health systems are fragile – lacking climate-trained personnel, resilient infrastructure, and adequate surveillance,” noted Stiell. To address this, delegates emphasised the need to integrate climate considerations into health sector planning at all levels, from hospital design standards to medical education curricula. The mantra of the day became “climate-proof every clinic” and ensure “no healthy people on a sick planet” – meaning a healthy future is impossible unless our health systems adapt to and mitigate climate change.

Policy Initiatives and Funding Commitments at COP30

Policymakers and organisations used COP30 to drive home the message that protecting health must be a core part of climate action – and they backed it with new initiatives (if not enough funding). Over 60 countries and numerous institutions endorsed the Belém Health Action Plan as a voluntary commitment to accelerate health adaptation. Initial supporters spanned Europe (e.g., France, Spain), small island states like Tuvalu, African nations from the Congo to Zambia, and others, including Canada, Japan, the UK, and Malaysia. Endorsing countries agreed to report on their progress by the Global Stocktake in 2028, using the WHO’s climate-health tracking framework (the ATACH initiative).

“There’s a very strong commitment from our government and ministers of health in this plan,” affirmed Brazil’s Health Minister Dr Alexandre Padilha. By COP30’s close, Brazil will have announced that over 80 nations and organisations had signalled support, describing the plan as a “blueprint… Now we have no alternative but to adapt and face climate change. If we don’t adapt, we will increase inequality…we will kill people”. Even the UNFCCC leadership embraced it:

“The Belém Health Action Plan gives us the blueprint. What we need now is sustained, coordinated, and well-financed action to turn its promises into protection for all,” said UN Climate Executive Secretary Simon Stiell. Importantly, health is becoming mainstream in climate policy: over 90% of national climate plans now include health considerations, and every National Adaptation Plan since 2024 addresses health risks, ranging from heat to infectious diseases – a remarkable shift toward health-centric climate planning.

However, financing emerged as the Achilles’ heel of these lofty commitments. The Belém plan was launched without any new funding pledges from governments attached. The only notable funding announcement was from a coalition of philanthropies (Wellcome Trust, Gates Foundation, Rockefeller Foundation, etc.), which committed $US 300 million toward climate and health initiatives. That one-time grant, while welcome, is a drop in the bucket. The UN Environment Programme estimates that low- and middle-income countries require at least $ US$11 billion annually for basic health adaptation, covering measures such as malaria and dengue control, climate-driven diarrhoea prevention, heatwave response, and surveillance upgrades. Even that $US 11B figure omits many costs included

in the Belém plan, such as addressing respiratory illnesses, malnutrition, mental health services, protecting healthcare workers, and decarbonising hospital systems. By 2050, the UNFCCC projects that global adaptation needs for health could reach US$277–29 billion per year. In stark contrast, current health-specific climate finance is estimated at only $US 500–700 million annually, roughly 0.5% of total climate finance.

“Health systems, already stretched and underfunded, are struggling to cope with these growing pressures… Existing finance falls short by billions. Without urgent investment, we will not be able to protect populations from escalating climate impacts,” warned Dr Marina Romanello of the Lancet Countdown on Health and Climate Change. Carlos Lopes, African Union envoy, lamented the “colossal deficit” in health adaptation funding. Indeed, many developing countries spend more on debt servicing than on healthcare, underscoring the need for grants and debt relief to fund climate-health needs.

To bridge this gap, COP30 negotiators and health leaders pressed for the integration of health into all climate funding mechanisms. They urged that a larger share of the promised US$100 billion or more in climate finance be earmarked for health adaptation (currently, only ~2% of adaptation funding goes to health). “The evidence is clear: protecting health systems is one of the smartest investments any country can make,” said Professor Nick Watts, chair of the COP30 health report advisory group. He noted that allocating just 7% of adaptation finance to health (up from ~2% now) could safeguard billions of people by keeping essential services running during climate shocks.

In line with this, the COP30 Special Report on Health and Climate Change calls on governments to integrate health into their climate plans (NDCs and NAPs), invest in resilient infrastructure (especially hospitals), and leverage the cost savings from low-carbon policies to reinvest in health capacity. It also highlights the need to empower communities and incorporate Indigenous knowledge in designing health responses, ensuring solutions fit local realities.

By framing climate change as “fundamentally, a health crisis”, COP30 succeeded in elevating health to the top tier of climate negotiations. Countries left Belém with a more explicit mandate: protect people’s health as a priority outcome of climate action. Achieving this will require following through on plans, such as the Belém Health Action Plan, with real resources. As Dr Tedros summed up, “This special report provides evidence of the impact of climate change on individuals and health systems, and real-world examples of what countries can do – and are doing – to protect health…

Now it’s time to turn commitments into action”. The challenge ahead is to turn the promises and piloted projects into scaled-up, well-funded programs that save lives. The hope emerging from COP30 is that health can become a unifying priority – a human-centric lens that drives faster climate ambition. In the words of one negotiator, “Humanity can only win this global climate fight if we connect stronger climate actions to people’s top priorities in their daily lives… and there are few higher priorities than our health”.

MSF teams navigate a landslide in Mexico to reach remote communities after intense rains. Climate-related disasters are striking vulnerable areas with increasing frequency, underscoring the need for resilient infrastructure and rapid health responses.

Clamming with bare feet was the norm, as was using a screwdriver to free mussels from the thick portions hanging onto the edges of the shore. Not one word was thought about dangers or pollution, and we ate everything eagerly. It was a naive and a fairly environmentally safe time. Not anymore.

Now we are faced with a new danger that we bring into the outdoors. We crave as a clean environment. Obviously researchers have now shown this to be a myth, and we are in the middle of a desperate time to try to save our health and that of Mother Earth.

The trail winds through pines; the canopy hushes in a small breeze. You breathe deeper, certain that fresh air will rinse the city from your lungs. After all, haven’t we been told that forest therapy is one of the best things for us? Aren’t we being encouraged to get outdoors more and to exercise there? When you exercise, what are you doing? Yes, you’re breathing deeply.

But the air that enters carries invisible companions: plastic microfibers — shed from jackets, socks, packs, and shoe soles — that ride as dust, cling to dew, and drift across ridgelines. We once pictured microplastics as an ocean problem. New evidence says they are also a trail problem — and, by extension, a human one. In high-use backcountry, hikers themselves are now a source of the very pollution we try to escape.

The invisible payload we wear (and leave behind)

In 2025, the UK’s National Oceanography Centre reported that roughly 70–71% of ocean microplastics are microfibres — the kind released from clothing, textiles, and fishing gear. If we wear synthetics, we help supply that stream.

Every stride, seam rub, zipper tug, and sock friction frees fibers; rain and runoff carry them from trails into streams and lakes, and wind returns them to us through the air. It is a frightening cycle of which we are a major part and of which we mostly remain ignorant.

Researchers and land managers have begun to quantify this “recreation shedding.” Early field work and event-based studies suggest synthetic apparel and soft-soled footwear can be significant microplastic sources in remote areas, with measurable spikes where foot traffic is heavy. In short: the cleaner and more popular a trail looks, the more likely it is experiencing a steady drizzle of microscopic fibers — some of which we re-inhale.

It’s not just what we wear on a hiking trip. Washing gear before or after a trip releases vast numbers of fibers into wastewater; many treatment plants aren’t designed to trap them. Those fibers eventually reappear in rivers, soils, and air, completing a cycle that leads back to our mouths and lungs. Even protected landscapes are not spared: atmospheric studies show microplastics raining onto remote parks and wilderness, carried aloft and dropped far from their sources.

What plastic specks do in bodies and minds

Finding microplastics around us is one thing; finding them inside us is another. Evidence now shows microplastics in human blood, lungs, placenta, testes — and even in brain tissue, including the olfactory bulb (our smell center), a route that may bypass normal protective barriers.

Lab and autopsy studies are cautious but sobering: particles can lodge in tissues, irritate cells, and carry attached chemicals — plasticizers, PFAS, and persistent pollutants — into places they don’t belong. How much of this causes inflammation? We know that inflammation is now one of the major factors in mental disorders. Could recreational products and clothing can be one of the main drivers of mental health issues?

Environmental and medical journals converge on several plausible pathways: inflammation and oxidative stress; respiratory irritation that may worsen asthma or COPD; and gut-barrier and microbiome changes. Early neuro-pathway findings — particles in brain tissue — raise concern about subtle cognitive or mood effects.

Quantification is evolving, but exposure is undeniable. Depending on our behavior and environment, we may inhale or ingest tens of thousands of particles annually — more if we rely on microplastic-shedding products or spend time in polluted outdoor air. The World Health Organization cautions that evidence remains incomplete, but the ubiquity of exposure and biological plausibility demand urgent attention.

How many times do these groups have to sound the alarm before we listen to it? None of this means we should stop going outside. It means we should go outside differently.

Walking wiser: reducing what we shed and what we breathe

The paradox is plain: hiking supports mental health and resilience, yet our gear can undermine the “clean air” we seek. The solution isn’t retreat; it’s redesign and habit change — at the individual, industrial, and policy levels.

1. Choose and use lower-shed gear. Favor natural or blended fibers (merino, heavier canvas layers) in base and mid-layers; keep delicate synthetics under abrasion-resistant shells; and pick harder-soled footwear when feasible. For synthetic pieces you love, wash them less often and use microfiber-capture tools (machine filters, washing bags), cold water, and gentle cycles. Are those detergent pods or sheets good for the environment, or is liquid better?

2. Rethink trail density and maintenance. Popular routes concentrate shedding. Land managers experimenting with seasonal rest days, reroutes, and boot-brush stations can reduce local fiber buildup. Citizen science — simple microfiber sampling kits — can also help prioritize hotspots.
Back policy that tackles the pipeline.

3. Support municipal upgrades to wastewater filtration, extended producer responsibility for textiles, and tire standards that reduce micro-rubber. Do you realize how much rubber is shed from all of the automobiles that are on our highways, and how that shed material works its way into the air we breathe?

4. Encourage manufacturers to develop low-shed knits and disclose shed-rates so consumers can compare products. Too often, we took the easy way out and chose cheaper fibers made from oil that are ending up damaging our health.

5. Can you begin to make an important contribution? In the meantime, protect your own lungs and gut: avoid heating food in plastic, use glass or metal bottles, keep air filters clean, and air-dry synthetics away from living spaces. On the trail, pack out all plastics — including frayed rope ends or shredded packaging.

We go to the woods to heal ourselves. That purpose still remains. But it now comes with a clearer view: we have turned clothing into dust, and dust into a supply chain that ends in our lungs. The solution isn’t to fear the trail — it’s to change what we bring to it and what we ask of those who make our gear.

Do the manufacturers of outdoor clothing have a commitment to exclude these dangerous materials from their manufacturing process? Every piece of rainwear, every boot, every backpack, everything we bring with us, brings destruction, but profit has sway over what is made and what is sold.

If we want the forest’s air to heal us, our footsteps must stop seeding it with what hurts.

The reality is more complicated. Brazil has staked its climate prestige on keeping COP30 in the Amazon. The UN’s official notice still lists the venue as Belém’s City Park and Hangar Convention Centre, 10–21 November. And the summit’s incoming president, veteran diplomat André Corrêa do Lago, has told critics there is “no plan B.” But here’s the catch: there may not be enough beds, and the beds that exist are often priced like Davos, not the delta.

This is not a hypothetical headache. After an emergency discussion at the UN climate bureau, Brazil faced pressure to shift at least part of the gathering — perhaps the leaders’ segment — out of Belém. Organisers demurred. Meanwhile, a government-backed booking platform showed rooms at $360 to $4,400 a night, and Brazil’s offer to reserve a handful of subsidised rooms for the poorest countries still overshot the UN per diem, a measure of daily allowance. The labels tell one story; the prices tell another.

Belém is racing to make it work. Brasília says roughly 4.7 billion reais (public and development-bank money) is flowing into airport upgrades, venues and transit fixes. The city boasts a 50% jump in scheduled flights for the COP window compared with last November. And organisers have added those cruise ships, docked at Outeiro, to ease the crunch. On paper, it sounds like progress. It isn’t — unless the pieces land on time and the access is fair.

Air travel is the hinge. The Val-de-Cans airport concession was amended to accelerate apron and terminal works to August — mere weeks before delegates land — though local reporting has flagged heat and construction delays that could complicate operations. You can feel the knife-edge timing in every press release and drone shot.

Why insist on Belém? Because the Amazon is the story. Brazil has engineered a conspicuous shift from oil-rich hosts in recent years to the world’s foremost carbon sink, and the Lula government wants negotiators to look deforestation drivers in the eye. To be fair, enforcement has helped Amazon forest loss fall to a nine-year low; at the same time, drought-fueled fires surged across vast areas last year. Both things can be true. Both matter for climate credibility.

And yet the city’s basic services and urban form were never designed for a 50,000-person, two-week jamboree. Belém routinely appears near the bottom of Brazil’s sanitation rankings; one widely cited analysis found only about 17% of residents connected to a sewage network. That’s not a moral failing — it’s a legacy of uneven investment, a reminder that climate summitry lands in real neighbourhoods with real pipes.

Then there’s the symbolism problem. In March, images of a new four-lane “Avenida da Liberdade” slicing through a protected green area ignited international outrage even as state officials argued the road was long planned and not a federal COP project. The paradox was brutal: clearing urban forest to ease access to a climate summit meant to protect forests. Belém’s defenders note wildlife crossings and solar lighting in the design; critics warn of the “fishbone” pattern of illegal expansion that often follows new roads. The Amazon rarely gives you a clean moral line.

Is there a fallback? Not officially. But something interesting is happening on Brazil’s southeast coast. Days before the COP opens, a COP30 Local Leaders Forum — mayors, governors, the people who move bins and buses — will convene in Rio de Janeiro, the city that hosted the 1992 Earth Summit that birthed the UN climate convention. It’s not the COP itself. It is, however, a tacit admission that a multi-city approach might be the most pragmatic way to include thousands who can’t afford Belém’s bottlenecks.

Meanwhile, business is hedging. Some companies and financiers are reportedly scaling back Belém plans, shifting events to São Paulo or Rio, where hotels, airports and meeting spaces are abundant. The risk is obvious: a hollowed-out core summit in the Amazon with a well-heeled, parallel circuit elsewhere. Climate diplomacy is bifurcated by bandwidth and room rates.

So should COP30 stay in Belém? Yes — with conditions. Because moving it would evacuate the point. The Amazon is where climate, food and health are braided so tightly you can’t tug one thread without the others tightening. Beef and soy supply chains that begin as pasture and clearings upstream ripple into supermarket meat cases and alternative-protein pitch decks far away. Fires and heatwaves feed respiratory illness and strained hospitals. Water security, flooding and sewage are not side stories; they are the texture of climate risk and resilience. Hosting the world here forces the agenda to stop floating above the canopy and come down to the ground.

But here’s what must happen, fast.

First, accessibility. Price gouging needs to be checked by moral suasion and market solutions. Brazil and the UNFCCC should expand the pool of capped-rate rooms, extend the cruise-ship model if needed, and underwrite shuttle networks from satellite lodging hubs so that least-developed countries and frontline communities aren’t priced out of the very talks that shape their futures.

Second, transparency. Publish a live, multilingual dashboard — rooms, prices, transit times, venue queues — so delegations can plan without panic. Fold in the Leaders’ Summit logistics as soon as they’re nailed down; people can’t book what they can’t see.

Third, split smart — formally. Take advantage of the Rio forum to design a sanctioned, high-bandwidth “twin” programme for side events and city-focused sessions, with guaranteed virtual bridges into negotiation rooms in Belém. Don’t let a thousand uncoordinated fringe conferences do this by accident. Organise it by design.

Fourth, leave a legacy that’s more than tarmac. If a highway is being built, hard-wire protection against the land-grabbing and settlement creep that so often follow new access roads. Pair every piece of concrete with measurable gains in sanitation, flood management and green jobs that outlast the motorcades. Otherwise, the summit’s footprint becomes the story, not its outcomes.

Fifth, connect the dots publicly. Use Belém to make explicit the chain from enforcement against illegal clearing (which Brazil has recently strengthened) to healthier forests, cooler cities, steadier rainfall, safer crops and fewer hospitalisations. If climate is a health crisis — as the WHO keeps saying — then COP30’s deliverables should read like a public-health plan as much as an energy one. People understand clinics and clean water. They vote with their bodies as well as their wallets.

Will this be enough? It has to be. Because relocating the COP to Rio or São Paulo might spare the delegates a humid queue and a pricey bed, but it would also spare the rest of us the jolt of seeing the climate’s front line up close. The labels tell one story; the science tells another. If we cannot convene in the Amazon without razing what makes it special — or pricing out the very countries that most need a voice — what does that say about the transition we’re building?

For now, at least, the plan is set: Belém or bust. Amazon will host the world. Whether the world shows up in a way that’s fair, focused, and honest is still up to us.

This highly respected journal has indicated that Earth has breached another boundary, and it’s in the oceans, turning toward a more acidic level than before. One cause is the enormous amount of carbon dioxide being pumped into the air, which has accumulated at levels not seen in millions of years. And the answer isn’t as simple as dumping some Alka-Seltzer into the oceans. Yes, I once worked for a public relations company that actually did suggest that huge tablets of Alka-Seltzer could be pushed into lakes that were being acidified by falling leaves. I really don’t know how that ended.

While scientists have long documented how ocean acidification harms coral reefs and shellfish, the ripple effects don’t stop with ecosystems. They extend to human health — our bodies, our communities, and our minds. The story of acidification is also a story of nutrition loss, respiratory dangers, and psychological stress.

Physical Health: When the Sea Stops Giving

The physical effects of ocean acidification are better understood and already visible.

• Seafood under threat
Fish and shellfish provide protein for billions of people, yet acidified waters compromise their survival. Scientific reviews have noted that fisheries will have reduced fish stocks available in the future, which means a decrease in income as well as available food for individuals in that area. For coastal regions where seafood is a daily staple, the health impacts could be profound.

• Toxins in the food chain
Acidified waters alter how metals and pollutants move through ecosystems. The Climate Change Post reported that the acidification of the oceans has increased toxic metals in marine life that are taken up, and then this food is consumed by us. Increased availability of toxic metals, such as aluminum, copper, and lead, may increase risks of neurological, kidney, and developmental disorders.

• Airborne risks
Harmful algal blooms — expected to worsen with acidification — can release aerosolized toxins that irritate lungs. According to news-oceanacidification-icc.org has noted: “Human exposure can occur through direct contact, ingestion of contaminated seafood, or inhalation of aerosolized toxins.” For those with asthma or chronic obstructive pulmonary disease, this may mean worsening symptoms and hospitalizations.

I’ve been in Florida, where the red tide was affecting their west coast. The air became heavy with the toxins from the algae blooms, and I coughed as never before. Anyone who didn’t have notification by the various hotel industries would have foolishly exposed themselves to danger by vacationing there. Of course, the red tide was not advertised widely, and people did go and did experience health issues.

The coastline where I was staying was heaped with seagrass and hundreds of snails that were dying, as well as a young shark. Along much of the western coast of Florida, the bloom was noted on maps for anyone who sought information like this.

• Waterborne disease
As protective ecosystems like seagrass beds degrade, pathogens spread more easily in warmer, more acidic water. Gastrointestinal illness and skin infections may become more common in swimmers and seafood consumers. Is this why we are seeing an increase in the malicious tissue-destroying bacteria in the water down in the South?

• Coastal defenses weakened
Coral reefs, mangroves, and seagrass meadows buffer storms and filter pollutants. As they erode, communities face a heightened risk of flooding, contaminated water supplies, and physical injury during extreme weather events.

Taken together, these effects suggest that acidification is not only an environmental issue — it is a public health challenge.

Mental Health: The Invisible Ripples

The psychological effects are less studied but just as real. Our connection to the ocean is emotional, cultural, and deeply human.

• Livelihood loss and stress
Fishing communities are among the most vulnerable. It’s obvious that the loss of income from fishing activities due to climate change will affect the mental health of these communities. Because of this finance-related stress, there will be an increase in depression, anxiety, and suicidal ideation. When a fisherman’s catch dwindles, the consequences ripple through families, schools, and local economies. So it’s not just the fishermen who will suffer, but the wide-ranging aspects of the entire community that will begin to falter.

• Cultural grief and solastalgia
When corals die or coastlines erode, people lose not only ecosystems but identity. The concept of solastalgia — grief caused by environmental change — describes the anguish of watching a beloved landscape transform into something unrecognizable. For Indigenous peoples and island nations, the loss of marine ecosystems undermines cultural continuity, traditional knowledge, and rituals tied to the sea. Currently, we are witnessing areas of the world where small communities are being submerged by ocean waves triggered by glacial melting associated with climate change.

• Loss of “blue space” benefits
  Healthy oceans function as “blue spaces” that restore calm, lower stress hormones, and encourage reflection. Studies consistently show that time spent near water reduces anxiety and boosts mood. It seems to be something comforting in this closeness to the water. Perhaps that stems from our evolutionary history.

When acidification bleaches reefs and empties coastal waters of life, the restorative power of the sea diminishes. In fact, researchers have noticed that a decrease in marine environments definitely has an impact on mental health.

• Climate anxiety in the young
Ocean acidification contributes to the broader phenomenon of climate anxiety. Young people in particular report distress, hopelessness, and fear about an uncertain future. Their anxiety is not irrational; it’s rooted in science and lived experience. Watching ecosystems collapse during formative years shapes their identity, mental health, and worldview.

• Inequality of burden

Marginalized coastal communities often bear the heaviest psychological load. Lower-income and minority communities may have fewer resources to adapt, leading to deeper stress and trauma.

In short, as oceans sour, human minds can suffer — sometimes quietly, but profoundly. There is no way around it unless we take drastic measures now to save our futures and those of our children and grandchildren.

A child who spends their childhood snorkeling through coral gardens will witness fish swimming between the living coral reefs. And that child will experience a profound shock when they see their former coral reefs transformed into lifeless, gray structures ten years later. The child will be left with either the fading memories of their wonder or the deep sorrow of losing something precious.

We now know that ocean acidification extends beyond its chemical and coral-related aspects. The process affects how people identify themselves while also threatening their sense of security and their mental ability to cope with challenges.

Protecting our oceans directly benefits human beings by safeguarding their physical health and mental well-being. If there is a slow, silent menace, it’s ocean acidification, which will inevitably affect us. However, the real question concerns our speed and empathy in taking action. When will the world realize that it MUST take action and CANNOT put it off?

As someone who works in communications, I’ve watched this all unfold with a growing sense of urgency, not just because it affects my work, but because it affects the work of the entire ecosystem, from startups trying to commercialize to scientists and innovators trying to solve our biggest planetary problems.

We often talk about climate solutions needing scale. But before they scale, they need visibility. They need resonance. They need the world to understand why they matter.

Communicators as Ecosystem Builders

Marketing and communications professionals in the climate space have always worn many hats: translator, storyteller, advocate, pressure-tester. But lately, I’ve started to see our role differently: we are infrastructure. The strength of the message can determine the strength of the movement.

In Israel, where I work with several climate tech companies, there is no lack of innovative ventures; startups are tackling everything from water quality and waste to sustainable food systems and energy efficiency. But too often, their stories don’t reach the audiences that matter.

Whether it’s a lack of media attention, limited investor familiarity, or messaging that doesn’t translate across markets, the result is the same: solutions that could make a global impact remain under the radar. Recent research highlights that communication barriers, including conflicting values and lack of emotional engagement, are among the biggest obstacles to climate action.

This is a stark reminder of how critical effective, strategic communications is for companies needing that break. We can’t assume the science will speak for itself. Our job is to help it connect.

Tell the Story Behind the Science and Tech

Technical breakthroughs are important. But if we don’t communicate the human stakes — if we can’t answer “why does this matter, now?” — then even the most brilliant solutions will get buried in white papers and pitch decks.

Take Amai Proteins, an Israeli innovator creating sweet proteins that offer a healthier alternative to sugar. On the surface, that’s a biochemistry story. But it’s also a public health story; excess sugar consumption is linked to rising rates of obesity, diabetes, and cardiovascular disease, all of which disproportionately affect low-income communities and strain healthcare systems.

It’s a consumer behavior story, too. Shifting tastes and nutritional preferences are driving the food industry to rethink its ingredients, and “clean label” alternatives are in high demand.

Even RFK Jr., despite the controversy surrounding many of his opinions, is taking on food system reform, moving to eliminate dyes and other additives and expressing that he’d love to see sugar eliminated from the American diet.

And yes, it’s a climate resilience story. Sugarcane and sugar beet farming are resource-intensive crops that require large amounts of land, water, and fertilizer, all of which are vulnerable to climate disruptions. Replacing them with a low-footprint, precision-fermented protein could ease pressure on ecosystems and improve food system sustainability.

These are opportunities for communicators to widen the frame and show how innovations intersect with public values. That’s how a single ingredient becomes part of a bigger story.

Make Climate Action “Cool”

In a world drowning in doomscrolling, climate urgency isn’t enough. People want hope, and they want to feel like they’re part of something that’s not just necessary, but exciting.

We saw this with Tesla and the early days of the electric vehicle market. EVs didn’t catch on because people suddenly got worried about emissions; they caught on because someone made them desirable.

As marketers, we have the power to do the same for other sustainable technologies: to make algae cleanup, biodegradable packaging, or atmospheric water generation feel like the future, not a compromise.

Speak Across the Divide

Many of us are communicating in fragmented markets. Different regions, different priorities, different regulatory directions. But the best messaging finds common truths: Clean water. Job creation. Community resilience.

If you start the story with a universally accepted premise, you’ve created a foundation of trust from which to build.

FireDome, an Israeli startup inspired by the country’s Iron Dome missile defense system, offers a perfect example of this approach. FireDome has developed an AI-assisted solution to detect and suppress wildfires autonomously, addressing the increasing frequency and intensity of such events due to climate change — something we saw clearly in Israel last week.

FireDome’s story tightly aligns a climate solution with community benefits. Everyone can agree that defending against wildfires is a necessity to protect property and lives.

That’s because the impacts are clear. Last year’s wildfire, which raged through Southern California, left entire communities in ashes, dozens of people killed, over 150 thousand people displaced, and damages estimated between $250-$275 billion, according to AccuWeather.

The value of proactively defending against wildfires quickly becomes obvious. The alignment between technological outcomes and community values exemplifies how climate tech can build long-term momentum and break through with target audiences by highlighting these tangible benefits.

Building Communications into the Business Model

Startups often focus intensely on R&D, product-market fit, and fundraising — and rightly so. But communications can’t just be an add-on, revisited only when there’s “good news” to share.

If we believe climate solutions are essential, then we need to treat communications as essential, too –not an afterthought or a slide at the end of the pitch deck, but a foundational part of the company’s infrastructure.

Strategic communications, embedded early, does more than explain what a company does; it shapes how it’s understood by investors, partners, policymakers and the public.

The right narrative can open doors, build credibility, and help a startup punch above its weight. Because climate solutions don’t just need to work. They need to land. And that’s where strong, unifying, value-driven messaging makes all the difference.

Now, a new global partnership between BlueGreen Water Technologies and Winrock International seeks to confront this escalating crisis head-on.

Announced in June 2025, the collaboration combines the BlueGreen groundbreaking water treatment technologies with Winrock strengths in community engagement and watershed expertise. The two organizations will pilot HAB mitigation projects in vulnerable water bodies worldwide, blending cutting-edge science with boots-on-the-ground collaboration.

Harmful algal blooms (HABs)are more than an environmental nuisance. When algae proliferate unchecked, they often release cyanotoxins, compounds linked to liver damage, neurological disease, and cancer. The danger is especially acute in communities with limited access to clean water infrastructure.

According to the Centers for Disease Control, exposure to HABs has been associated with severe illness in humans and animals alike, and outbreaks have increased significantly in frequency and intensity over the last two decades.

“These blooms undermine the fundamental right to clean, safe water,” says Eyal Harel, CEO and co-founder of BlueGreen Water Technologies. “They endanger health, food supplies, biodiversity, and climate stability.”

Based in Houston with global reach, BlueGreen Water Technologies has emerged as a global leader in treating HABs. Its signature product, Lake Guard®, utilizes controlled-release hydrogen peroxide granules to target toxic algae directly, restoring ecological balance without harming aquatic life.

What sets the technology apart is its speed and scalability. Many affected water bodies rebound in just days after application. Moreover, by collapsing algal blooms rather than rupturing cells, Lake Guard helps prevent toxin release and accelerates the natural sinking of biomass, contributing to measurable carbon sequestration. In Utah’s Mantua Reservoir, BlueGreen intervention captured nearly 13,000 metric tons of CO₂-equivalent, verified by third-party environmental assessors.

While its carbon market potential has attracted investor interest, the BlueGreen mission remains rooted in planetary and public health.

Winrock International, a global nonprofit, brings decades of experience in environmental sustainability, agricultural development, and clean water access. The organization has a reputation for working alongside local communities and government agencies to implement nature-based solutions that balance ecological and social needs.

Aaron Sundsmo, Winrock Associate VP of Agriculture and Water, emphasizes that addressing HABs isn’t just about treating symptoms—it requires upstream solutions. “Community engagement, stakeholder trust, and long-term strategies to reduce nutrient pollution are essential. That’s where our strengths align with BlueGreen’s vision.”

By partnering with Winrock, BlueGreen gains an experienced ally in building locally responsive frameworks. Together, the two will integrate chemical treatment with watershed restoration, sustainable agriculture, and environmental education.

The partnership will launch its first pilots in high-risk regions identified through water quality data, community needs, and ecological urgency. These initiatives will pair BlueGreen’s precision treatments with Winrock-led efforts in stakeholder coordination, regulatory navigation, and long-term land use planning.

The collaboration also aims to generate actionable environmental data to inform policy and attract sustainable investment. With HABs projected to intensify globally, scalable, science-backed, and socially grounded models like this will be vital.

BlueGreen is also in active trials with marine research partners, including Florida’s Mote Marine Laboratory, to adapt its technology to fight ocean-based HABs like red tide, which devastate marine biodiversity and coastal economies.

This partnership reflects a growing recognition that health and environmental outcomes are interlinked. Climate change, industrial agriculture, and pollution are not isolated crises—they converge in ways that challenge traditional silos of action.

“Solving water contamination issues requires more than a technological fix,” says Harel. “It demands a unified approach—combining innovation, policy, and people.”

In a world where over 2 billion people already lack safely managed drinking water, solutions that restore water health while building resilience and equity are more than innovations—they are imperatives.

The BlueGreen-Winrock alliance represents a forward-looking strategy for a world in ecological flux. It’s a model that others in the global health, sustainability, and climate tech sectors would do well to follow: technology married to trust, environmental impact driven by community inclusion.

Water is life. Safeguarding it—from HABs or any threat—must be a shared priority. This new partnership is a promising start.

For me, chewing gum is a momentary indulgence.

It relieves stress.

But am I missing something?

Here’s my concern after reading a new study:

Chewing gum, whether natural or synthetic, can be a significant source of microplastic ingestion.

Honestly, I suspect that I need not be particularly concerned as the amount of microplastics is low.

It is an unfortunate reminder of how we have poisoned our environment.

A Pilot Study

Could a single piece of gum put me in harm’s way?

A new study offers limited evidence that the answer may be yes.

Researchers discovered that a single piece of gum can release 637 microplastic articles per gram.

Synthetic gums release a similar amount of microplastics as natural, plant-based ones.

I’ll be okay, right?

After all, I only chew gum for a few minutes; when the taste goes, so does the chewing gum.

But there is this:

The majority of microplastics are released within eight minutes of chewing.

One more problem: I am heading to Singapore this year.

Have you heard about Singapore’s infamous ban on chewing gum?

Singapore: A Sticky Situation (Solved)

On January 3, 1992, Singapore banned gum manufacture, sale, or importation.

Upon arrival, all must declare any gum or face the consequences.

But why such a drastic measure?

Singapore’s gleaming, efficient Mass Rapid Transit (MRT) system became an unexpected battleground.

In the sweltering months of summer 1991, the gum lodged itself between train doors and caused malfunctions.

These incidents weren’t minor inconveniences; they stopped trains, forced passengers to disembark, and disrupted the city’s vital transportation network.

Beyond the MRT, the careless disposal of chewing gum created a persistent and costly cleaning nightmare in public spaces, from cinema seats to housing.

Does It Matter?

And so we come to this vital question: Does it matter that my chewing gum has bits of microplastic in it?

• Current Scientific Understanding: As of now (April 1, 2025), the direct health impacts of ingesting microplastics at the levels found in chewing gum (or even from other common sources like water bottles, food, and air) are not well-established or fully understood. Research is ongoing, but there isn’t conclusive evidence yet to say that the amount ingested from occasional gum chewing causes specific harm or is clinically relevant.
• Ubiquitous Exposure: Microplastics are unfortunately everywhere in our environment. Chewing gum is just one potential source among many we encounter daily.
• The Environmental Reminder: Your point is well-taken — it is a stark reminder of widespread plastic pollution and its infiltration into seemingly everyday items.
• Conclusion on Risk: While the study shows gum is a source of microplastic ingestion, current scientific consensus doesn’t label this specific exposure route as a significant, defined health risk compared to other environmental exposures. It’s a low-level exposure in the broader context, though the long-term effects of cumulative microplastic exposure are still an active area of research. So, while not zero, the immediate risk from the gum itself appears minimal based on current knowledge.

I’m not giving up my occasional gum (except in Singapore).
