Nature is at the very core of the changing climate challenge. And it can be a major part of the solution. Natural systems absorb nearly half of all human-generated carbon dioxide<\/a>, making them one of our most powerful tools for long-term sustainability. As we look for more innovative and cost-effective ways to prevent hotter and hotter days, stabilize weather patterns, and pull more carbon out of the air, NbS can lead the way \u2013 creating pathways to resilience that benefit both planetary and human health. <\/p>\n Forest and waterfalls on a stream in Spring. Nature in balance leads to reduced emissions, lower anxiety, fewer weather- and environment-related hospital admissions, lower storm damage costs, a decline in mortality during heatwaves, and stronger community cohesion.<\/p>\n Byron Jorjorian<\/p>\n Planetary Health is Public Health<\/p>\n Forests, wetlands, and oceans collectively form the planet\u2019s largest carbon sink<\/a>, meaning that they absorb more carbon from the air than they produce, which helps cool the climate and buffers communities from disaster. But, when these ecosystems start to degrade, the effects are immediate and compounding. Deforestation accelerates flooding and droughts. Wetland loss erodes coastal defenses and drinking-water security. Soil degradation undermines food systems. And biodiversity loss destabilizes disease regulation. The World Health Organization and International Union for Conservation of Nature describe this convergence as a \u201cplanetary emergency<\/a>,\u201d linking nature\u2019s ecosystem decline directly to diminished human health and wellbeing \u2014 specifically to increases in respiratory illness, vector-borne disease, malnutrition, and mental health burdens.<\/p>\n The clinical and scientific evidence linking declining environmental health to human disease is extensive. The spread of malaria<\/a> and ebola<\/a>, for example, has been traced to deforestation and land conversion that increased human-wildlife contact. Elevated carbon dioxide has been shown to reduce the nutrient content of staple crops, driving 10-18% declines in protein, iron, and zinc in wheat and rice<\/a>. Likewise, urban heat<\/a>, air pollution<\/a>, and climate anxiety<\/a>, have been found to compound the physiological and psychological stresses of modern living.<\/p>\n Planetary health becomes public health. It\u2019s increasingly clear that ecosystem integrity underpins the basic conditions for life \u2013 clean air, safe water, nutritious food, and stable climate regulation. When these systems falter, so do we. But nature-based strategies help to more comprehensively address these challenges. They improve air and water quality, enhance food security, support mental health, and increase access to natural medicines. They enhance the health of our communities. Here\u2019s proof:<\/p>\n In Louisville, Kentucky, Green Heart Project researchers, working with The Nature Conservancy and the National Institutes of Health, have been testing whether neighborhood greening can reduce cardiovascular risk. After planting more than 8,000 trees and shrubs in low-income neighborhoods with high pollution exposure, they found residents\u2019 high-sensitivity C-reactive protein (hsCRP) levels \u2014 a key inflammation marker \u2014 were lower by 13-20%<\/a>. These reduced levels correspond to a nearly 10-15% reduction<\/a> in the risk of heart attacks, strokes, or cancer. The controlled clinical trial proved a quantifiable, positive public-health return on a green investment, providing a replicable model for linking environmental interventions with measurable human health metrics.<\/p>\n A growing body of research highlights that urban trees are powerful public health and environmental assets\u2014linked to lower obesity and disease rates, improved stormwater control, cooler neighborhoods, higher property values, reduced pollution, and stronger biodiversity.<\/p>\n The Nature ConservancyNew York City\u2019s Watershed Protection Program provides clean drinking water to 9.5 million people, saving billions in treatment costs and maintaining ecosystem function<\/a>. The initiative began in the 1990s, as the state and federal regulators sought to meet the requirements of the Safe Drinking Water Act. Rather than build another water treatment plant at the cost of $8-10 billion, the city invested $1.5 billion over 10 years<\/a> in preserving its forested watershed and restoring critical habitats to protect its water at the source. The water supply is among the cleanest in the world.Dune restoration efforts<\/a> in coastal New Jersey, including The Nature Conservancy\u2019s work to restore the South Cape May Meadows Preserve, played a vital role in reducing flooding and storm damage when Hurricane Sandy hit the Atlantic Coast in 2012. A 2017 analysis estimated that coastal wetlands saved more than $625 million<\/a> in direct property damages during Hurricane Sandy and reduced annual property losses by nearly 20 percent in Ocean County, N.J. Research has shown that coastal marshes can reduce wave energy by over 50%<\/a>, and are estimated to provide storm protection valued at $23.2 billion<\/a> annually in the U.S. <\/p>\n Great Blue Heron standing in a marsh. The Nature Conservancy estimates that protecting and restoring forests, wetlands, and grasslands could deliver up to 37 percent of global emission reductions needed by 2030 to keep global temperature increases below dangerous levels.<\/p>\n Byron Jorjorian<\/p>\n These three examples show that NbS do more than slow climate change \u2013 they work to prevent illness, strengthen public health systems, and build community resilience. Thus, it makes sense that healthy ecosystems are the very foundation of healthy, resilient communities. By protecting and preserving balance within ecosystems, we aren\u2019t just conserving nature. We\u2019re preventing disease, improving quality of life, and creating conditions for every community to thrive.<\/p>\n Oceans: Life-support for you and me<\/p>\n The term nature-based typically conjures up trees, forests, soil, streams, and wildlife. To those living on the coasts, the first thing that comes to mind is the ocean. And for good reason. Oceans are the planet\u2019s largest life-support system, and thus one of our most powerful nature-based solutions for human health and well-being. Covering more than 70% of Earth\u2019s surface, they regulate climate, generate half the oxygen we breathe, and absorb about one-third of all human carbon dioxide emissions each year. They also capture more than 90% of the excess heat trapped by greenhouse gases, buffering us from even more extreme warming. Healthy oceans sustain billions of people through food, medicine, and livelihoods; they regulate the water cycle and reduce disease. Coral reefs, the \u201crainforests of the sea,\u201d support a quarter of all marine life and protect nearly 200 million people from coastal storms.<\/p>\n So how do we protect an ocean? By reducing pollution and curbing overfishing; by expanding marine-protected areas that allow ecosystems to recover. It includes restoring mangroves, seagrasses, and coral reefs, cutting plastic waste, and minimizing to the extent possible fossil fuel emissions that drive warming and acidification. Protecting oceans safeguards both planetary and human health.<\/p>\n Innovative Financing for Nature<\/p>\n Despite clear benefits, NbS remain drastically underfunded. Current global investments in NbS total approximately USD $200 billion per year<\/a>, less than half what the United Nations Environment Programme estimates is needed annually by 2030 to effectively address biodiversity loss, land degradation, and the effects of hotter days. This financing gap is a substantial shortfall; but looked at differently it also represents a vast opportunity for action \u2014 to innovate and align modern financial systems with proven planetary and public health pathways.<\/p>\n A study by The Nature Conservancy, conducted with other institutional partners, found that if all 21 nature-based solutions investigated were fully implemented \u2014 from restoring forests and grasslands to a range of agricultural practices \u2014 they could prevent or sequester more than one-fifth of annual U.S. greenhouse gas pollution.<\/p>\n The Nature Conservancy<\/p>\n Harnessing Carbon Markets<\/p>\n High-integrity carbon markets offer one promising path to scale. In 2023, global carbon pricing revenues reached USD $104 billion<\/a>, with more than half directed toward climate and nature initiatives. The voluntary carbon market, projected to grow to USD $100 billion<\/a> by 2035 if barriers are effectively addressed, enables companies to fund verified ecosystem restoration while accelerating their own decarbonizing efforts. Contrary to perceptions that carbon credits are \u201clicenses to pollute,\u201d evidence strongly suggests that firms purchasing voluntary offsets are in fact more likely to reduce gross emissions<\/a> than peers who do not.<\/p>\n Innovating Through Sovereign Debt<\/p>\n Beyond carbon markets, new financing mechanisms are transforming national debt into another creative tool for conservation. Many of these initiatives have been pioneered by The Nature Conservancy working with partners. Belize\u2019s 2021 \u201cBlue Bond<\/a>\u201d initiative, for instance, refinanced USD $364 million in debt in exchange for protecting 30 percent of its marine area by 2026. Similarly, Barbados\u2019s 2022 debt conversion<\/a> generated USD $50 million for regional conservation and ocean stewardship over 15 years. The model\u2019s success, particularly in a non-distressed economy like Barbados, shows its potential for replication across a wider range of nations. More broadly, though, these innovations reveal how smart financial restructuring can measurably advance sustainable environmental outcomes without compromising economic sovereignty. <\/p>\n Taken together, these sovereign nature\/blue-bond conversions have committed on the order of $1.3\u2013$1.45 billion in dedicated conservation funding (in Seychelles, Belize, Barbados, Gabon, Ecuador\u2019s Gal\u00e1pagos and Amazon regions, and The Bahamas), with The Nature Conservancy\u2019s Nature Bonds portfolio alone projecting about USD $1 billion unlocked to help improve management of approximately 242 million hectares of land, freshwater, and ocean. That is scale achieved though creative modern finance mechanisms.<\/p>\n Valuing Ecosystem Services<\/p>\n Payments for Ecosystem Services (PES) offer another powerful mechanism. By compensating communities for stewarding natural assets that generate shared benefits, PES programs convert ecological value into tangible economic incentives. New York City\u2019s Watershed Agricultural Program remains the gold-standard example. Rather than building a costly filtration system, the city pays farmers in the Catskills to protect upstream water quality, resulting in decades of clean, unfiltered drinking water for millions of residents.<\/p>\n River under blue skies.
