Worlds biggest problems?

I found this at a site calling itself the worlds biggest problems portal:

Economic Collapse : Fragilities in the current global economy could tip the developed world into conditions not seen since the 1920s.

Peak Oil : Petroleum has powered the modern world for almost 100 years; today, many industry insiders say the we may be reaching a permanent peak in oil production.

Global Water Crisis : Over the last 50 years the human population has nearly tripled, while industrial pollution, unsustainable agriculture, and poor civic planning have decreased the overall water supply.

Species Extinction : Certain species that human beings depend upon for our food supply are going extinct; if their numbers fall too low we may face extinction ourselves.

Rapid Climate Change : While the debate rages on about the causes of climate change, global warming is an empirical fact. The problem is both a curse and blessing, in that people from different cultures will either have to work together or face mutual destruction.

Economic calamities simply create opportunity.

Peak Oil, a problem, but also an opportunity.

Global water crisis, umm yeah this is actually is a big problem...

Species Extinction... this is hard to calculate... but some populations are disappearing rapidly and that is very disturbing... bees for example, we can't live long without them.

Climate change... they say this like we had something to do with it, I find that unlikely. the climate changed back and forth between cold and warm with out us for a long time and we are well within the norm. Mostly to do with that giant fireball we call the sun.
