A new United Nations science report says nature is in trouble and 1 million species of plants and animals are at risk of going extinct.

Development that’s led to loss of habitat, climate change, overfishing, pollution and invasive species is causing a biodiversity crisis, scientists say in a new United Nations science report released Monday, May 6, 2019.
“The biological diversity of this planet has been really hammered, and this is really our last chance to address all of that,” Lovejoy said. “We are indeed threatening the potential food security, water security, human health and social fabric” of humanity, Watson told The Associated Press. He said the poor in less developed countries bear the greatest burden.— Turning forests, grasslands and other areas into farms, cities and other developments. The habitat loss leaves plants and animals homeless.
Fighting climate change and saving species are equally important, the report said, and working on both environmental problems should go hand in hand. Both problems exacerbate each other because a warmer world means fewer species, and a less biodiverse world means fewer trees and plants to remove heat-trapping carbon dioxide from the air, Lovejoy said.
The IUCN calculated in March that 27,159 species are threatened, endangered or extinct in the wild out of nearly 100,000 species biologists examined in depth. That includes 1,223 mammal species, 1,492 bird species and 2,341 fish species. Nearly half the threatened species are plants.The report comes up with 1 million species in trouble by extrapolating the IUCN’s 25% threatened rate to the rest of the world’s species and using a lower rate for the estimated 5.
The report goes beyond species. Of the 18 measured ways nature helps humans, the report said 14 are declining, with food and energy production noticeable exceptions. The report found downward trends in nature’s ability to provide clean air and water, good soil and other essentials.
