The world is losing migratory species at alarming rates

The world is losing migratory species at alarming rates

Inside Climate News reports:

Humans are driving migratory animals—sea turtles, chimpanzees, lions and penguins, among dozens of other species—towards extinction, according to the most comprehensive assessment of migratory species ever carried out.

The State of the World’s Migratory Species, a first of its kind report compiled by conservation scientists under the auspices of the U.N. Environment Programme’s World Conservation Monitoring Centre, found population decline, a precursor to extinction, in nearly half of the roughly 1,200 species listed under the Convention on Migratory Species (CMS), a 1979 treaty aimed at conserving species that move across international borders.

The report’s findings dovetail with those of another authoritative U.N. assessment, the 2019 Global Assessment Report on Biodiversity and Ecosystem Services, that found around 1 million of Earth’s 8 million species are at risk of extinction due to human activity. Since the 1970s, global biodiversity, the variation of life on Earth, has declined by a whopping 70 percent.

Migratory species face unique and heightened risks because they rely on connectivity among multiple ecosystems spanning national borders and because their predictable migration patterns make them vulnerable to poachers. The State of the World’s Migratory Species, released Monday, found that one in five species on the CMS list is threatened with extinction—and for listed fish, that number is a stark 97 percent.
