This is my problem with all that - there are people, sane voice like Peter Schiff who understand what happens with the economy and they are few; there are climate scientists who will tell you what's going to happen with the climate in the business-as-usual scenario, etc.; there are oil experts like Matt Simmons who are warning about Peak Oill; there are the Paul Ehrlichs of the world who are outspoken about overpopulation. And they get the closest to doing it, but basically an extremely limited number of people is putting it all together and seeing the connections between all these disasters
