The Global Assessment Report on Biodiversity and Ecosystem Services is a report released on 6 May 2019 by the United Nations' Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, on the global state of biodiversity. The report found that, due to human impact on the environment in the past half-century, the Earth's biodiversity has suffered a catastrophic decline unprecedented in human history.[1] An estimated 82 percent of wild mammal biomass has been lost, while 40 percent of amphibians, almost a third of reef-building corals, more than a third of marine mammals, and 10 percent of all insects are threatened with extinction.
