Bio-diversity. It’s assumed to be a good thing. But is this BBC News article a pointer to a misunderstanding of nature?

Nature requires that vulnerable species — species least able to change to survive — die out. Extinction should be allowed to happen.

Humanity has decided that extinction is a bad thing because humanity is so often the cause. But when it is not, or is in only a tenuous way, it is not to be lamented that a species might become extinct — this is evolution in action.

Though, of course, as the Now Show said on Saturday, there’s nothing to fear from Bird Flu if you’re not in agreement with Richard Dawkins — bird flu must mutate (read: evolve) for there to be any danger to humans transmitting the disease to other humans. And that can’t happen can it?!
