Are we living in the last century of our civilization?

Nope. There's no such thing as a "fair share" of resources. No one owns the Earth, so no one can allocate me my portion. And, as for resource shortage, there's plenty of good farmland in Zimbabwe...it's knowing how to use it.

2100? What a bunch of pessimistic blather. I have no doubt that as a society we could come together and wipe out this whole planet by 2050.
