Climate Change and Human Activity Push Nearly 2,000 More Species to Threatened List

First assessment of world's freshwater species shows 25% at risk, while conservation efforts show promise for two antelope species.

Climate change and human activity have added nearly 2,000 new species to the threatened list, according to a report by the International Union for Conservation of Nature (IUCN).
Among the endangered species are the Central South Pacific and East Pacific green turtle populations, which are suffering from warmer waters and rising sea levels.
The Atlantic salmon population has decreased by 23% between 2006 and 2020 due to warmer temperatures and human activity such as dams, water pollution and logging.
The first assessment of the world's freshwater species shows 25% are at risk of extinction due to decreasing water levels, dams and overfishing.
Despite the rising number of endangered species, conservation efforts have improved the status of two antelope species: the saiga antelope and the scimitar-horned oryx.
