American Apparel Organics - very cool! the brand against sweat shops now also has organic cotton clothing
and Killing My Lobster isn't really very related to earth friendliness, but they are ridiculously funny. the earth needs humor too i spose. if this hilarious comedy group is coming to your town, see them! your sides will ache, i promise.
