Hazel Thornton, Programme Officer for the United Nations (UN) Environment Programme World Conservation Monitoring Centre. 2021 marks the start of the UN Decade on Ecosystem Restoration – a ten-year effort to prevent, halt, and reverse the degradation of ecosystems on every continent and in every ocean. Join us as we explore the how, what, where, when, and why of this global movement that aims to tackle poverty, combat climate change, and prevent mass extinctions through the restoration of degraded ecosystems.
