...and then there's the matter of the coral reefs dying off. The marine biologists have been studying this and they credit this phenomenon to an increase in the temperature in the waters where coral reefs occur. Apparently it's a small increase, but enough to kill off coral. They're not all dead yet, but they're dying fast.

I watched (and taped part of) a show by Bill Moyers the other night about the subject of the damage that is being done to the earth by human activity, and some solutions to some of the problems associated with it. The scientist who was talking about the coral reefs dying off said that it's the first instance in recorded history of an entire type of eco-system dying off.

By the way, that was an excellent show, in my opinion, and I think it's worth buying a tape of it from PBS or whoever produced it.
