1 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.
Although extinction is a natural phenomenon, it occurs at a natural âbackgroundâ rate of about one to five species per year. Scientists estimate weâre now losing species at 1,000 to 10,000 times the background rate, with literally dozens going extinct every day [1]. It could be a scary future indeed, with as many as 30 to 50 percent of all species possibly heading toward extinction by mid-century [2].
