A new assessment from the International Union for the Conservation of Nature finds that one in four mammals are threatened with extinction. Overall, the report says 32,441 species could face extinction if current trends aren't reversed.

“This assessment shows that 1 in 4 mammals are facing extinction, and although we don’t prefer to think of ourselves as animals, we humans are mammals,” said Tierra Curry, a senior scientist at the Center for Biological Diversity. “We have to take bold and rapid action to reduce the huge damage we’re doing to the planet if we’re going to save whales, frogs, lemurs and ultimately ourselves."

In updating its assessment, IUCN looked at 120,372 species for which there is enough information to determine their conservation status.

Global figures for the 2020-2 IUCN Red List of Threatened Species:

• TOTAL SPECIES ASSESSED = 120,372
• (Total threatened species = 32,441)
• Extinct = 882
• Extinct in the Wild = 77
• Critically Endangered = 6,811
• Endangered = 11,732
• Vulnerable = 13,898
• Near Threatened = 7,211
• Lower Risk/conservation dependent = 189 (this is an old category that is gradually being phased out of The IUCN Red List)
• Least Concern = 62,033
• Data Deficient = 17,539

Last year the United Nations estimated that 1 million species worldwide face extinction if humans don’t act quickly to save them. Scientists around the globe are calling for countries to preserve 30 percent of lands and waters by 2030 and half by 2050 to abate the extinction crisis.

“We know what we need to do to end extinction,” said Curry. “At this point it’s a matter of political will to rapidly move away from fossil fuels, stamp out the wildlife trade and overhaul the toxic ways we produce food. We really can do all of these things, but we need world leaders to stand up and do them.”

Amphibians continue to be the most imperiled group of animals, with 41 percent threatened worldwide, IUCN said. Around 14 percent of birds and 40 percent of conifers are also threatened.

Although not included in the IUCN update, multiple species in the United States face extinction, including monarch butterflies, wolverines, red wolves, Southern Resident killer whales and dozens of freshwater fishes and crayfishes from southeastern states, the Center said in a release.

The Center recently released a groundbreaking plan to fight extinction. The Saving Life on Earth plan calls for $100 billion for species; for half the Earth to be protected for wildlife; and for dramatic cuts in pollution and plastics.
