Biodiversity is the root of all life, both on land and below water. It has an impact on human health, providing the air that we breathe, the water we drink, the food we eat, natural disease resistance, medicines, as well as climate change mitigation. The emergence of COVID-19 has proved that when we destroy biodiversity, we destroy the system that supports human life. Nature is sending us a message. Aptly, this year’s theme for World Environment Day is biodiversity – a concern that is both urgent and existential. Protecting nature and reversing degradation to ecosystems is at the heart of the EU Green Deal and is the rationale for the new EU biodiversity strategy for 2030.
