The Sixth Extinction

Thanks to Rick Eliot for this article.

The author says that the carrying capacity of humans on earth is variously estimated at 13-15 billion. I think that is way high. It’s hard to imagine we could double human impact and still be growing. Nevertheless, the article is informative.

Can we stop the devastation of our planet and save our own species? We are in a biodiversity crisis – the fastest mass extinction in Earth’s history, largely due to:

About 30,000 species go extinct annually.
There is little doubt left in the minds of professional biologists that Earth is currently faced with a mounting loss of species that threatens to rival the five great mass extinctions of the geological past. As long ago as 1993, Harvard biologist E.O. Wilson estimated that Earth is currently losing something on the order of 30,000 species per year – which breaks down to the even more daunting statistic of some three species per hour. Some biologists have begun to feel that this biodiversity crisis – this “Sixth Extinction” – is even more severe, and more imminent, than Wilson had supposed.
