How many animals go extinct each year?
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.
