Human health cannot be separated from the health of the planet. The destruction of nature has an especially significant role in driving disease outbreaks.
We must protect nature
Protecting nature is critical to preventing future pandemics. Ecosystems function similarly to the human body: When they are healthy, they are more resistant to disease. But when forests and other natural ecosystems are destroyed or degraded for agriculture, cattle ranching, urban development and other activities, sick and stressed wildlife are forced into closer contact with farmed animals and people. This creates the conditions for diseases to spread quickly.
Research shows that infectious disease emergence is on the rise — and land-use change, particularly deforestation, is a major driver. This carries tragic consequences for people’s lives and livelihoods. As people encroach deeper into undisturbed forests — creating opportunities for humans to interact with wildlife, whether intentionally or not — they risk getting exposed to diseases, some of which could lead to pandemics. Moreover, experts expect climate change to exacerbate the emergence of infectious diseases, as warming weather shifts the distribution of animals that can spread infectious diseases.
Now is the time to create policies and invest in strategies to prevent outbreaks before they even start.
Investing in nature yields significant returns
A pandemic such as COVID-19 costs millions of lives and trillions of dollars. For just a fraction of that amount — approximately US$20 billion per year — the world could significantly reduce the emergence of new infectious diseases and save countless lives, according to a study co-authored by Conservation International scientists.
Funding would support four pandemic prevention strategies:
Despite studies revealing that many pandemics are fueled by the destruction of nature — including seminal research by Conservation International — sufficient action has not been taken to mitigate future pandemics by protecting high-risk ecosystems. From working with governments to reduce deforestation and strengthen their biodiversity conservation laws, to supporting Indigenous peoples and local communities in their efforts to manage their territories, Conservation International is helping to prevent pandemics by addressing some of the key drivers that cause the emergence of infectious diseases.
How can we prevent future pandemics? It starts with stopping the destruction of forests and the illegal wildlife trade. Protecting nature is key for a healthy future.

Protecting nature to prevent pandemics costs just 1% of fighting them
Experts say the yearly cost of future pandemics will be a staggering US$ 2 trillion. For just 1 percent of that cost, the world could prevent pandemics at their source by protecting nature, according to a new study co-authored by Conservation International scientists. Read more »

Conservationist: Protecting nature an ‘investment’ in our health
In recent decades, wildlife populations have faced catastrophic decline. Over that same period, diseases that spread from animals to humans have rapidly multiplied. This is no coincidence, says one prominent conservationist. Read more »
