We like Worldchanging a lot; they are really smart and get to the core of a wide range of environmental issues. They are a non-profit and are running a new fundraising campaign, where photographer Ed Burtynsky and a foundation have donated up to $ 50,000 each, and will match funds from the rest of us, raising $ 3 for every $ 1 we donate.
This treehugger just donated personally and we hope our readers will. ::Worldchanging
