Raoul,
I AM an environmentalist, the point I was making is that exploration of the universe means leaving human artifacts on other planets... I see nothing wrong with that and I hope in a few millenia the whole galaxy is "littered" with our probes.
I am only criticising the ignorant radical environmentalists that dont think their positions through... I do think we are in for disaster unless we start acting responsibly, but the extreemists like ELF are making it harder for the rational people to be heard....

There IS global warming...That is just a fact, those that deny it are as far out there as the nuts in ELF. We understand the mechanism, we measure it happening, and we are seeing its effects... the question is how to deal with it... the extreemists on both sides are preventing any useful action from being taken....
