Extinction The rapid loss of species we are seeing today is

estimated by experts to be between 1,000 and 10,000 times higher than the natural extinction rate. means the rate of species extinctions that would

occur if humans were not around experts calculate that between 0.01% and 0.1%

of all species will become extinct each year 2 million different species on our planet: between

200 and 2,000 extinctions occur every year 100 million different species on our planet: between

10,000 and 100,000 extinctions occur every year
