We hear about inventors, artists, and scientists who are trying to design our way to a more sustainable environment. An engineer creates bacteria that will excrete fuel; an architect designs the house of the future, shaped like an egg; a photographer finds mutant frogs in your backyard; and a rock star complains about "counting carbon credits when we could be doing lines." Plus, Joni Mitchell on writing the reigning anthem of the environmental movement.
