At immediate issue was whether the Park Service should have done more to keep bears away from humans, but what was revealed as the trial unfolded was just how fruitless our efforts to regulate nature in the parks had always been. The proceedings drew to the witness stand some of the most important figures in twentieth century wilderness management, including the eminent zoologist A. Starker Leopold, who had produced a landmark conservationist document in the 1950s, and all-American twin researchers John and Frank Craighead, who ran groundbreaking bear studies at Yellowstone. Their testimony would help decide whether the government owed the Walker family restitution for Harry's death, but it would also illuminate decades of patchwork efforts to preserve an idea of nature that had never existed in the first place.  In this remarkable excavation of American environmental history, nature writer and former park ranger Jordan Fisher Smith uses Harry Walker's story to tell the larger narrative of the futile, sometimes fatal, attempts to remake wilderness in the name of preserving it. Tracing a course from the founding of the national parks through the tangled twentieth-century growth of the conservationist movement, Smith gives the lie to the portrayal of national parks as Edenic wonderlands unspoiled until the arrival of Europeans, and shows how virtually every attempt to manage nature in the parks has only created cascading effects that require even more management. Moving across time and between Yellowstone, Yosemite, and Glacier national parks, Engineering Eden shows how efforts at wilderness management have always been undone by one fundamental problem--that the idea of what is "wild" dissolves as soon as we begin to examine it, leaving us with little framework to say what wilderness should look like and which human interventions are acceptable in trying to preserve it.    In the tradition of John McPhee's The Control of Nature and Alan Burdick's Out of Eden, Jordan Fisher Smith has produced a powerful work of popular science and environmental history, grappling with critical issues that we have even now yet to resolve.

    By talking through a hundred or so items, Mike Berners-Lee sets out to give us a carbon instinct for the footprint of literally anything we do, buy and think about. He helps us pick our battles by laying out the orders of magnitude. The book ranges from the everyday (foods, books, plastic bags, bikes, flights, baths...) and the global (deforestation, data centres, rice production, the World Cup, volcanoes, ...) Be warned, some of the things you thought you knew about green living may be about to be turned on their head. Never preachy but packed full of information and always entertaining.
