how many animals are going extinct?
178183
There are now 41,415 species on the IUCN Red List, and 16,306 of them are endangered species threatened with extinction. This is up from 16,118 last year. This includes both endangered animals and endangered plants.
974687
In the past decade, 467 species have been declared extinct (though they might have gone extinct in decades prior), according to the global authority on species conservation status, the International Union for Conservation of Nature, or IUCN.

Regardless, scientists agree that today's extinction rate is hundreds, or even thousands, of times higher than the natural baseline rate. Judging from the fossil record, the baseline extinction rate is about one species per every one million species per year.

60% of world's wildlife has been wiped out since 1970. Well over half the world's population of vertebrates, from fish to birds to mammals, have been wiped out in the past four decades, says a new report from the World Wildlife Fund.

Critically endangered is the most severe status. In 2012, the IUCN Red List featured 3079 animals and 2655 plants as endangered worldwide.

There are now 41,415 species on the IUCN Red List, and 16,306 of them are endangered species threatened with extinction. This is up from 16,118 last year.

Since the 16th century, humans have driven at least 680 vertebrate species to extinction, including the Pinta Island tortoise. The last known animal of this subspecies, a giant tortoise nicknamed Lonesome George, died at the Galapagos National Park in Ecuador in 2012.

Of course, when we speak of overpopulation, we specifically refer to humans. In fact, human activity is causing massive die-offs of the other species. ... The United Nation's intergovernmental report on biodiversity found that a further 1 million animal and plant species are now at risk for extinction.

Two events occurred that killed off 27% of all families, 57% of all genera and 60% to 70% of all species. Together they are ranked by many scientists as the second largest of the five major extinctions in Earth's history in terms of percentage of genera that became extinct.

Frog Mass Extinction on the Horizon. The world has lost at least 200 frog species since the 1970s, and hundreds more will face extinction in the coming decades, according to new research published last week in the Proceedings of the National Academy of Sciences.

Many animals living on Earth today are endangered, which means they are at risk of becoming extinct (dying out) on Earth. Endangered animals include tigers, rhinoceroses, orangutans, turtles, and many more. Their numbers have already been greatly reduced and only a few now live in the wild.

Scientists announced that three bird species vanished from the Earth for good in 2018. While 2018 didn't see much wildlife extinction, the Earth is losing animal species at 1,000 to 10,000 times the natural rate. Below are species that we lost last year, and some that we're on the brink of losing.

But if the upper estimate of species numbers is true - that there are 100 million different species co-existing with us on our planet - then between 10,000 and 100,000 species are becoming extinct each year.
661187
They estimate that more than 1 million species will be lost by 2050. The results are described as "terrifying" by Chris Thomas, professor of conservation biology at Leeds University, who is lead author of the research from four continents published today in the magazine Nature.
650879
About two dozen species were declared extinct (or nearly so) in 2019, although the total number of species lost this year probably numbers in the thousands. Scientists typically wait years or even decades before declaring a species well and truly extinct, and even then only after conducting extensive searches.

Deforestation and tree-clearing is the major cause of habitat loss for many threatened and endangered species. In Asia, this includes orangutans, tigers, rhinos and elephants, some of which are on the brink of extinction.
504378
Our species caused 322 animal extinctions over the past 500 years, with two-thirds of those occurring in the last two centuries, according to a paper published in a special issue of the journal Science this week.
