RESCUING THE PLANET

A passionate argument for protecting the world’s rapidly shrinking wilderness.

A century ago, 15% of the Earth’s surface was farm or pasture; today, it’s 77%. Many experts maintain that this loss of natural land as well as the “sixth extinction” and all the effects of climate change have passed the point of no return. Former New Yorker staff writer Hiss disagrees, and he describes a campaign to protect 50% of the world’s land, a plan that may strike many as absurd—until they read his cogent argument. Three great forested areas—Siberia, the Amazon, and the North American Boreal (in Canada and Alaska)—make up most of the world’s wilderness. “Siberia is 60 percent cut over,” writes the author, “and so is more than 20 percent of the Amazon, where the rate of deforestation is spiking.” The Boreal, however, is 85% intact. Since human activities account for less than 40% of our continent, and 15% is already protected, the author’s plan is feasible. Readers accustomed to a litany of doom will discover a modest amount of good news. Many well-financed environmental organizations are working toward the 50% goal, and, unlike the case with reducing global warming, governments tend to be amenable. The best scenarios have occurred in Canada and Australia, which have returned large amounts of land to previously displaced Native populations. The U.S. government is unlikely to buy into the entire plan, but a combination of activists, naturalists, and a few billionaires are making progress. Hiss illustrates his thought-provoking arguments with a handful of North American projects, including a major expansion of the Appalachian Trail, rejuvenation of New Jersey’s Pine Barrens, restoration of the vast pine forests in the Southeast, and conversion of Yellowstone into a Greater Yellowstone protected area, essential to preserve its diminishing species. With its combination of passion, inspiration, and rigor, this makes a good companion to Bill Gates’ How To Avoid a Climate Disaster.

Excellent natural history and more optimistic than usual.
