The World Wide Fund for Nature warns that
there is, in fact, a very serious biodiversity crisis.
And illustrates this with an unreferenced "scientific analysis"
These experts calculate that between 0.01 and 0.1% of all species will become extinct each year.
From this, they conclude that - depending on the estimate of how many species there are, up to 100,000 species are becoming extinct every year.
Are their uncited calculations accurate? Do experts think that the extinction rate is per annum is between 0.01% and 0.1%?
