Tony Hiss is a really good writer and takes what could be a very dry and depressing subject, and yet left me with hope. Because of my adoration of EO Wilson and my career conserving land, understanding more about the goal to conserve half the earth seemed worth my time. Hiss “sought out people who consider 50 by ’50 practical; I wanted to see the problems they face and the prime spaces where it could work, the pieces of the continent ready to be folded in”(5%). And that’s what this book is about.
Why protect at least half of the earth?
— “According to a calculation by E. O. Wilson, America’s foremost biologist, protecting 15 percent of the land guarantees the survival of only a quarter of the species with which we now share the earth. But push that figure up to 50 percent of land and sea, and up to nine-tenths of species will survive”(3%).
— And it’s very feasible in North America. “Here in North America there’s still room to spare, and 50 by ’50 can move ahead without crowding or displacing or confining anybody because human activities (cities, suburbs, farms, mines, and all the rest) so far account for less than 40 percent of the continent”(3%)
— Even our massive national parks are not enough. “Many species of mammals are disappearing from North America’s national parks solely because the parks—even those covering hundreds of thousands of acres—are too small to support them.” The data came from William D. Newmark, an ecologist who surveyed fourteen national parks in the United States and Canada…“As roads, housing development and deforestation take hold around park boundaries, they isolate animal populations in regions that seemed like spacious havens when the parks were established 70 to 90 years ago”(36%). This is rooted in island biogeography, which is talked about extensively in this book.
The reader is brought to some amazing landscapes where amazing work is being done.
—“The North American Boreal Forest, mostly in Canada, partly in Alaska, is the largest and most intact wildness left in the world”(4%). “…Siberia, the Amazon, the Boreal—the Big Three, as they are sometimes known—are all about the same size. But in Siberia roughly 50 percent has been lost, and so has more than 20 percent of the Amazon, where the rate of deforestation is spiking. The Boreal is nearly 85 percent intact”(4%).
— “the Muskwa-Kechika, sometimes referred to as North America’s Serengeti and the continent’s biggest well-kept secret. It’s a British Columbia wilderness seven times the size of Yellowstone”(42%).
— The one remaining Waverly Oak remaining in Boston, accessible by the three-quarter-mile-long Waverley Trail. It’s at least 600 years old.
— Banff National Park, which somehow “still has all the species it did when European settlers arrived in the nineteenth century”(71%).
— Paint Rock, Alabama. “So many kinds of trees thought to have been lost to the world manage to survive here”(74%). It apparently has the biodiversity of the Smoky’s in a much more compact area.
Indigenous Protected Areas are a great tool!!
—“Indigenous people constitute only 5 percent of the planet’s population but they dwell on a quarter of the land. Now that they’re finding a voice and being listened to, there’s a chance to get the balance right, a chance for the world to be helped on its journey”(19%).
— “I loved the sentiment of Aboriginal Australians about the land. ““Working on country,” as opposed to “in the countryside,” is more than a local quirk or semantic distinction; the phrase has special meaning for Aboriginal Australians, a way of indicating that the land is alive and lived with, not in. “People say that country knows, hears, smells, takes notice, takes care, is sorry or happy,” Deborah Bird Rose, an ethnographer who’s spent years working with Aboriginal people, says in her book Nourishing Terrains. “Country is home, and peace; nourishment for body, mind and spirit; heart’s ease.””(17%).
— “Indigenous people live on a vast majority of the intact land the world needs to protect. If more countries, perhaps as many as a dozen, acknowledge the rights of Indigenous citizens and work in partnership with them to set up Indigenous Protected Areas (IPAs), these areas could rival in scale those currently in Canada and Australia, and lead on to multinational constellations of IPAs. Steve Kallick, working through the Resources Legacy Fund, told me, “This could take hold as one of the central environmental rights and human rights campaigns of the century, profoundly altering how we treat each other and all the other species we live with.””(96%)
While in Florida recently, I saw a gopher tortoise, and this book taught me a lot about them. Apparently they are ecosystem engineers, like beavers, transforming their environment. “At least 360 animal species take shelter in the burrows up to fifty-two feet long and twenty-three feet deep excavated by shy and dusty gopher tortoises”(80%). But they are declining because people cover their holes and trey can’t dig up (only down).
I even learned a new word - but that’s not to say his writing is inaccessible. It was very layperson friendly. Vagility, “meaning the ability of wide-ranging animals like wolves and caribou to move freely and without restriction across a landscape that isn’t now and never was too small for them”(12%). For one male grizzly in the greater Yellowstone ecosystem to have vagility, he needs to be able to roam around on 900,000 acres (according to the gps data biologists have collected).
In Kim Stanley Robin son’s book on the High Sierra’s, he talks about this book
“E. O. Wilson named this project Half-Earth, and in the book of that title he advocates for leaving half the Earth’s land and ocean empty of humans, and thus free for the wild creatures, as part of humans living up to our moral responsibilities to our cousins on this planet, and also passing along a viable home to our descendants, who otherwise might be given a world wrecked by our ecocide. Tony Hiss has just published a book called Rescuing the Planet that recovers the pre-Wilsonian history of this idea of leaving big fractions of the land free of human alterations, and he marshals the scientific justification for this policy, and describes its many manifestations in the world today.”
