This number is not based on evidence. I clicked through the links on this number, and it traces back basically to guesses that say if there are 100 million species on earth and if 0.1% of them go extinct every year then, well, that divides into that number. If you try to look up specifics - birds, for instance - you'll find that far fewer bird species have gone extinct in this century so far than the pace of the last century[0]. Which is actually encouraging! We are up against big odds but the immense efforts put into conservation are not hopeless - it's working!
