How many species of birds went extinct in 2020?

How many bird species should be becoming extinct per 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.

when did conodonts go extinct?

how are mass extinctions good for some species?
In effect, a mass extinction cleans the slate, creating new evolutionary niches which promote a wide range of species, increasing biodiversity, competition and in some cases increasing complexity in organisms as they try to carve out their niche in the new world. We are an example of the aftermath of mass extinctions.

how can overpopulation lead to extinction of a species?
As the human population grows, we destroy more habitat, kill more animals for food, release more pollution into the atmosphere, soil, and water supply, all of which increase the rate of extinction of species.
why do extinctions occur?
Extinction occurs when species are diminished because of environmental forces such as habitat fragmentation, climate change, natural disaster, overexploitation by humans, and pollution, or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).

How many species went extinct as a result of the first ice age?
About 86 percent of species living at the time became extinct as a result of a severe ice age, which lasted about 1 million years. It was probably triggered by a great mountain-building continental collision that exposed silicate rocks to erosion.
