Elephants have such sad expressive faces that it is hard to imagine how anyone could harm them. They have drawn lips and sagging shoulders; a long, drooping demeanour; sad, knowing eyes capable of laying on the guilt. Yet, it would appear that guilt is not enough to save them. Eighty years ago there were perhaps 6 to 9 million African and Asian elephants. Today there are roughly half a million left. Day by day, they are getting closer to extinction.
