Tbh I think that global warming is a myth looking back at history every however many thousand years the earth goes through a period of warming, wich soon cools back to the general trend, and we are o the verge of one of these periods. But the fact that evrybody is changing there ways and redusing emisions can do no harm, so all we are doing is reducing our (very small) impact on our planet. The truth is humans are still only a small part of the earth, and we are not as influencial as we think we are.
Super awesome song ^^
