Book excerpt: Who will protect our planet from the corporations, governments, and individuals who pollute, destroy, and devastate our natural world? Step forward a fresh new breed of passionately purposeful environmental lawyers, whose client is the Earth itself. At the head of this legal army stands James Thornton, who takes governments to court, and wins. In Client Earth, we travel from Poland to Ghana, from Alaska to China, to see how citizens can use public interest law to protect our planet -- and our future.
