4. 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 http://worldwildlife.org/
