What do you call an environmentalist who supports logging and condemns the protests against genetically modified foods? Some green activists label Patrick Moore a liar. Others compare him to Judas. Strong words to describe a founding member of Greenpeace and a veteran of the frontline against everything from whaling to nuclear waste. Moore's life is no simple equation. Having spent half a lifetime courting danger and arrest, he became disillusioned with the mainstream environmental movement, accusing it of abandoning science and following agendas that have little to do with saving the Earth.
