Ecosystem Restoration Is Good for Your Health
Rising public-health costs and the significant global disease burden – exacerbated by the COVID-19 pandemic – strengthen the case for the world to move toward ecological restoration. The benefits to planetary and human health will easily justify the cost.
NEW DELHI – Humanity currently faces multiple, interlinked existential crises. The catastrophic consequences of climate change, ecological degradation, and biodiversity loss have cascading knock-on effects on human health and well-being. As the COVID-19 pandemic illustrates, ecosystem damage can contribute significantly to a global public-health emergency. But scientists are also increasingly finding that ecological restoration, by reversing the threats to soil, biodiversity, water, and other ecosystem services, can deliver major health benefits.
There have been many attempts to understand the nexus between ecological degradation and human health. A recent study of over 6,800 ecosystems across six continents provided further evidence that deforestation and extinction of species will make pandemics more likely. Ecosystem damage also leads to water contamination, creating breeding grounds for infectious diseases. Similarly, soil degradation not only reduces agricultural productivity, but also has been linked to disease and increased mortality.
The emergence and spread of zoonotic diseases like COVID-19 are closely associated with the health of ecosystems. For example, 75% of emerging infectious diseases are zoonotic, caused by unsustainable use of natural resources, factory farming of animals, and other industrial-scale anthropogenic factors.
