Even in the series "Planet Earth" they say it's a natural process... but even with global warming, another ice age will still come many many years from now.

To me, this doesn't mean that global warming is a hoax and that we should continue to be as wasteful as we can and any means to prevent/reduce waste is unnecessary and costly waste in itself.

or that cfc's and other ozone reducing chemicals should continue to be used without control.

same with carbon monoxide, nitrogen dioxide, soot and other irritants produced by coal/fossil fuels being "insignificant" - acid rain does have an impact on humans and wildlife

Finally, since all animals generate C02, the thought process of extinction of species actually reduces global warming (if in fact is exists) is benificial is selfish, biased and irresponsible. If Corals die, then algae/plankton and then fish etc. 70% of the earths surface being a wasteland would suck and impact climate changes dramatically. (algae produce 90%+ of atmosphere O2 etc.)

Humans aren't doing the world a favor by replacing species with themselves.
