A fifth of the world\’s known mammals, a third of its amphibians, more than a quarter of its reptiles and up to 70% of its plants are under threat of extinction according to the red list of threatened species, the latest annual survey compiled by the International Union for Conservation of Nature.
Well, yes and no.
The truth is:
The IUCN estimates that nearly 17,300 of the world\’s 47,677 assessed species are under threat of extinction.
Still a hugely high number and so on however, what they\’re actually saying is that one fifth of the mammals they\’ve included in their list are in danger of extinction. For the total number of species, 17k out of that 47k.
But the actual number of species is somewhere between 1.5 million and 100 million.
