The theme for World Environment Day, 5 June 2020 is biodiversity — a call to action to combat the accelerating species loss and degradation of the natural world. One million plant and animal species risk extinction, largely due to human activities. Hosted by Colombia, in partnership with Germany, World Environment Day urges us to rethink how our economic systems have evolved and the impact they have on the environment. These are issues the world cannot lose sight of even as we tackle the coronavirus pandemic and the ongoing climate crisis. The World Environment Day website provides latest updates on registration, online events, the agenda and live feeds.
