I think the next big problem is global warming.
Sure, everybody knows about it, but not many seem to realise that we're talking about eventual human extinction in our children's lifetime.
And it's almost definite that nothing will be done about it until it's too late. Human nature.
Over-population is also a worry. When half the world is starving to death we'll need another planet to grow crops to feed them and not long after that we'll need another two and so on.
