I know it's a typo, but I kind of like the idea of eco-chambers. It made me think of the Biosphere 2 project. I'd love to see somebody take another crack at that.

To answer your question - $1 million would fund two or three skilled people full time for a year. So the problem has to be relatively small. I'd maybe spend it on an ad blitz to try to find homes for dogs and cats currently in shelters in a small number of cities.
