Climate chaos and pollution, deforestation and consumerism: the crisis facing human civilization is clear enough. But the response of politicians to it has been cowardly and inadequate, while environmental activists have tended to favor single-issue campaigns rather than electoral politics. _The No-Nonsense Guide to Green Politics_ measures the rising tide of eco-activism and awareness and explains why it heralds a new political era worldwide. DEREK WALL is a former principal speaker of the British Green Party. He is the author of numerous books, including _Babylon and Beyond: The Economics of Anti-Capitalist, Anti-Globalist and Radical Green Movements_.
