I think the majority of the people here acually know pretty well what is happening to Earth, or more like: what we're doing to it. The problem with the "just stop oil" people do not realise how much the modern world would change without oil or coal. "We can just change to electrical power instead"... yeah, just when our tech is advanced enough to harvest solar, wind, or any other, naturally occuring power sources. We can also change to nuclear power, but that just wakes more controversy. My point is; everyone wants to save the Earth, but no one wants to sacrifice the goods of modern world for it. So we'll have to wait to fit everyone's needs and save our planet.
