Our world is NOT dying, it is reorganizing. Much like it has for thousands of years before now. And BTW, since the norther cap is melting at an alarming rate, wouldn't New York and all the other coastal cities be in danger of some sort of flooding, yet there are no reports of anything like that.
The homeless and runaways will be resiliant IF they needed to be, much like they are today. They will find a way to live.
The joke is people like you who think that people can't find the solution to problems.

@TheOne: reread your post.....
Dinosaurs didn't use natural resources(eg. oil), um does the term fossil fuels mean anything?
