The Environmental Leadership Program has a GREAT fellowship opportunity, and they're accepting applications now! It's not specifically legal but it's cool!
"The Fellowship Program targets emerging environmental and social change practitioners eager to connect their specialized work to larger environmental and social concerns. ELP is committed to selecting a class of Fellows that represents diversity of race and ethnicity, gender, sector, sexual orientation, education levels, professional background, values and traditions, and environmental issue expertise."
There are a lot of cool-looking retreats involved :)
