Mankind must go green or die, says Prince Charles

130. Even civilization's fall isn't at all inevitable.

Yeah, I know, sounds all bubbly, right? But when you think about it, the world's still a really, well, big place. I mean, yes, it's true that some areas will likely suffer far worse than others; after all, much of Africa, the Middle East, and South Asia do only hang on by a thread, while at least we can fall back on some resources.

As for the death tolls? The most realistic worst-case scenario I can think of, due to climate change, if we make that the only factor, would probably be around 1-1.5 billion by 2100. Of course, with other factors involved, such as civil strife, wars, etc., as well as possible epidemics, I'd say that number would go up to about 2-2.5 billion. Hell, I'll go down the pessimists' route and up that number to 2.7-2.8 billion. Definitely not pleasant at all, under any circumstances but that's really only in the absolute worst case scenarios.
