These experts calculate that between 0.01 and 0.1% of all species will become extinct each year.
If the low estimate of the number of species out there is true – i.e.
that there are around 2 million different species on our planet** – then that means between 200 and 2,000 extinctions occur every year.
What percent of animals are endangered?
The species endangered include one in four mammals, one in eight birds, one third of all amphibians and 70% of the world’s assessed plants on the 2007 IUCN Red List are in jeopardy of extinction. The total number of extinct species has reached 785 and a further 65 are only found in captivity or in cultivation.
How many animals went extinct in 2018?
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.
Why are so many animals going extinct?
Species become endangered for two main reasons: loss of habitat and loss of genetic variation. A loss of habitat can happen naturally. Dinosaurs, for instance, lost their habitat about 65 million years ago.
Are 200 species going extinct every day?
Scientists estimate that 150-200 species of plant, insect, bird and mammal become extinct every 24 hours. This is nearly 1,000 times the “natural” or “background” rate and, say many biologists, is greater than anything the world has experienced since the vanishing of the dinosaurs nearly 65m years ago.
