Globally, monitored population sizes of mammals, fish, birds, reptiles,
and amphibians have declined an average of 68% between 1970 and 2016,
according to World Wildlife Fund’s (WWF) Living Planet Report 2020.
Populations in Latin America and the Caribbean have fared worst, with an
average decline of 94%. Global freshwater species have also been
disproportionately impacted, declining 84% on average. As an important
indicator of planetary health, these drastic species population trends
signal a fundamentally broken relationship between humans and the
natural world, the consequences of which—as demonstrated by the ongoing
COVID-19 pandemic—can be catastrophic.
