What are you doing to help the environment?

If your a beleiver that an astriod came down and wiped out the dinosaurs, plus creating a ice age (which I do) then it is clear that the planet earth can take a mean left hook.
Global Warming will essentially destroy us and probably alot of the beasties that run, squirm, and slid around us.
It would be the end of alot of things for sure-but not the earth.
Anyhoo, history has shown us that the most complex organisms have the shortest shelflife, so we are pretty much for the bin anyway. By the time human exsistence is done and dusted, it will account for a tiny tiny tiny amount of earths time.
Comparitable a nettle rash.

What is something you do on a regular basis or as a way of life that puts less strain on global resources?
