Published in 1971, still relevant, vintage John McPhee, three stories about David Brower, extreme conservationist. A 360 review of his character and work in action, as seen in dialogue with three of his opponents. As usual, McPhee takes a dispassionate, closely observed role in the debate: he gets to know all the characters in their milieu, and uses his observations to clarify issues and show the politics (in the broadest sense) of conservation at work. And thanks to him, lucky reader, so do you.
