This has always puzzled me. As a colleague of mine puts it: "Imagine what would happen to us if rainfall was a thousand times more than normal? What if snowfall were a thousand times more than normal? What if rates of disease transmission for malaria or HIV/AIDS were a thousand times higher than they are now? That is what is happening to plant and animal biodiversity today."-- Russell Mittermeier
