- From THIS human's standpoint, I'm not too worried about whether we can
- adjust to the changed climate. Humans are remarkably adaptable and very
- good at manipulating their environment. Especially those human populations
- that can afford air conditioning. What does worry me is how many of our
- fellow biota can make the necessary adjustments.

- How about those (probably) millions of species that really won't affect our
- survival one way or another? Do we kiss them off? IMHO, far too many
- biologists and ecologists have been trapped into economic arguments to
- justify species protection. There's a hell of a lot of ecological
- redundancy if you reduce an ecosystem to its functional attributes. Far
- more honest if we acknowledge that we're making a value judgement;
- those plants and animals are valuable because most people VALUE them,
- (several posters in sci.environmental excepted) not for what they might do
- for us.

- Me either.
