The good guys and the bad guys in environmental issues are often determined by which side you favor.
But the murkiness of good/bad and right/wrong is brought into sharp focus in Summer Brennan's book The Oyster War: The True Story Of A Small Farm, Big Politics, And The Future Of Wilderness In America.
It concerns a decades-old oyster farm in California, a federal effort to protect sensitive lands, and the ability of anybody involved in an extractive industry to protect or enhance the environment.
