As far as global warming. I don't think CO2 emissions are the problem either. Like some said about volcanos and stuff. My main concern is the rainforest. It's like the planets lungs and by choppin it down at the fastest rate ever seen. It's like smokin a carton of cigarettes a day. There are many global systems at a delicate balance. It's only a matter of time before we(human race) fuck up something. If the rainforest goes earth would turn in to a venus like planet. Hot as fiznuk.
