i do know that CO2 is an important gas in our atmosphere and that it is only in small quantitys. i was using it as an example. i could have just as easilty said nitrogen, helium, neon, etc etc. the only gas we can live on in a pure enviroment of is oxygen.

i myself am not a hunter or fisher the only time ive really shot at something is with a camera. i do however love the out doors and nature. so that makes me an envirmentalist. i dont want to destroy that wich i love so much.

also i heard long ago that it wasnt the CO2 levels but water vapor causing global warming. ive also heard ancient CO2 deposits, methane gas, aliens, and dont forget cow farts all are causing global warming.

i dont know if we did it or if its a natural cycle of things, there seems to be no absolute conclusive evidense either way. i dont think there ever will be. we can only look at fossils, rocks, ice etc. etc. and get a really good idea of whet happened and make superb educated guesses and show very convincing evidence. i can show you all day long that the earth warmed up once if not many times before i can show you the cause but i cant show you the why. i do like to beleive that its just natural

anyway this subject has always made my brain hurt
