And there are the feel good charities that move toward sustainability, such as Heifer http://www.heifer.org/ and its ilk. Even on Glee - Finn gave vegan, Jewish Rachel a sow!
But I'm thinking about giving to some groups that push the envelope. Non-profits that teach small scale sustainable agriculture, like Ecology Action http://www.growbiointensive.org/ based in wonderful Willits, but reaching folks in Africa, Latin America, the Middle East...
And to groups that watchdog global food justice, like the Oakland Institute http://www.oaklandinstitute.org/ doing particularly important work these days exposing land grabs in Africa.
I'm not going to repeat the cliche about giving a fish, but I will ask:
How many times can we multiply our charitable dollars to work toward food justice?
