From CNN Money:
Think humanity's problems are too big to be tackled by business? Think again. Here are nine companies showing how we can make millions saving us from ourselves.
(Business 2.0 Magazine) -- If you've read the news lately, you know the scale of the problem. Catastrophes that once seemed far away are creeping uncomfortably close to our lifetimes. The permanent polar ice cap will disappear by 2040. The seas could be practically devoid of fish by 2048. Manhattan and Miami will be flooded by 2050. Add in widespread disease and famine, and you have a script for the apocalypse.
But before you get too depressed, consider that business - until now part of the problem - is scrambling for answers. Clean-technology investments soared by more than 50 percent in the first three quarters of 2006.

For the following stories, we identified the most intractable problems facing the human race. Beyond climate change, there are the pollution troubles: mountains of trash, haze-choked skies, and dirty water. Disease includes not just viral epidemics but also new strains of ultraresistant bacteria. And our global food problem isn't just about Third World famine; it's also about conditions that could wipe out the $158 billion fishing industry.
It made for a disquieting list - until we found companies developing workable, scalable solutions. For each, we teased out not just the size of the potential windfall but also entrepreneurial insights from the pioneers. Finally, we offer a look at technologies too new to be commercialized but that could emerge in just a few years. Our most disastrous century yet? Maybe. It could also be our finest hour....MORE
