i doubt you actually read it with the time it took you to respond. If you had, you would realize what an insignificant effect humans have on global climate changes. I referance this video for you Ivan which shows you not only the diffrence between an argument and a contradiction, but gives you pointers on how to construct an argument vs just contradicting. when you can provide scientific evidence that refutes mine, i would be happy to engage you in an educated debate

also i do not deny that cleaner water, air, soil, ect ect is a bad thing, but the topic of discussion was simply global warming. So limited to that scope, the arguments for cleaner water, air ect ect do not apply to this topic.
