Billions of cars all producing green house gases doesn't affect the environment? At all? Bold claim there. Where's your evidence?

We may be speeding it up, even then, this is normal. Destruction of the environment is terrible and we should try to preserve it, but we are still coming out of an ice age. As long as there is perma frost on the earth... Then we are technically still in an ice age. Even if man made global warming is real, no point in slowing it down. btw more shit comes out in one volcano blast than all the shit man has put up in the air over our history. Desertification is what we should be worried about, as more of the environment is polluted and we cut down forests.
