23 animals declared extinct in 2021, including types of bird and fish

A total of 23 species could be removed from the Endangered Species Act (ESA) due to extinction, following a proposal from the U.S. Fish and Wildlife Service.

The list includes several birds, two types of fish, and eight species of freshwater mussels that have sadly gone the way of the dodo.

A 2019 report from the UN found that one in four species are at risk of extinction, with human activities “threatening more species now than ever before”. Devastatingly, marine pollution has increased tenfold since 1980.

The UN report also listed the five main drivers of “unprecedented” biodiversity and ecosystem change over the past 50 years: changes in land and sea use; direct exploitation of organisms; climate change, pollution, and invasion of alien species.

So which species could be removed from the ESA, and how long have they been extinct?

Secretary Deb Haaland said that climate change and natural area loss is pushing more and more species to the brink, and now is the time “to lift up proactive, collaborative, and innovative efforts” to save America’s wildlife.

In a statement, Haaland said: “The Endangered Species Act has been incredibly effective at preventing species from going extinct and has also inspired action to conserve at-risk species and their habitat before they need to be listed as endangered or threatened.

“We will continue to ensure that states, Tribes, private landowners, and federal agencies have the tools they need to conserve America’s biodiversity and natural heritage.”

Although the ESA came too late for the 23 species listed in this article, it has been successful at preventing the extinction of more than 99% of species listed.

The U.S. Fish and Wildlife Service said that in total, 54 species have been delisted from the ESA due to recovery, and another 56 species have been downlisted from endangered to threatened.

There are plans to down list or delist 60 species due to successful recovery efforts as well, so it’s not all doom and gloom thankfully.
