It’s not uncommon for people to long for nature as it once existed, before human progress and civilization reshaped the Earth and its ecosystems. But George Monbiot thinks it’s wrong-headed to try to return the natural world to an earlier, more pristine state.

Monbiot is one of Britain’s most provocative environmentalists, and his column in The Guardian is one of the most widely read and influential in Britain. In his new book, Feral: Rewilding the Land, the Sea and Human Life, he argues that nature is neither sentimental nor nostalgic for its own past, but if left alone, it is more resilient, resourceful and creative than we appreciate.

He defines rewilding as a mass restoration of the natural world. Where land, such as farmland taken out of agricultural production, becomes available, the rewilding process would see human infrastru

cture, from fences to drainage ditches, ripped out and some species re-introduced.

The idea is that humans would kick-start ecosystem processes, then stand back and let nature do its own thing and rebuild healthy wild places.

"One of our tendencies," Monbiot told Sunday Edition guest host Laura Lynch, "is to try to manage and control and see ourselves as stewards of the land, and to take an Old Testament view of dominion that we’re responsible for all the animals and plants. Well, nature did pretty well for the three billion years before we turned up, and it could do pretty well again if we learned to interfere less."

He also points to the ability of top predators to completely transform ecosystems, such as when wolves were recently re-introduced to Yellowstone National Park – if humans keep their hands off.

"The whole ecosystem was changed by the wolves and that’s one of those wonderful, serendipitous surprises that to me is what nature should be all about. Nature is not just a collection of species, it’s all the weird stuff that happens between those species."

In the process, humans can relieve what Monbiot calls ecological boredom and reconnect with the natural world, recapturing an essential and exhilarating wildness within ourselves.

Message to Canadians

The Canadian edition of Feral also includes a sort of open letter to Canadians.

People who are familiar with Monbiot will not be surprised to learn that he is not a fan of the oil sands industry, and his message to Canadians is particularly trenchant, writing that Canada is "one of the world’s most beautiful and sophisticated nations," but that it is being "ransacked by barbarians."

In his conversation with The Sunday Edition's Laura Lynch, he didn’t back away from that kind of rhetoric.

"At the moment, this highly cultured, sophisticated, wonderful nation seems to be descending into a thuggish petro-state which appears to be governed by the tar patch, and its politics seem to suffer from the oil curse, as so many countries suffer from when they have found big reserves of fossil fuels. And wildlife has suffered greatly as a result, natural resources of all kinds are suffering greatly, and so are those who love nature.

"It’s almost as if Canada is ripping up its most precious natural assets in exchange for assets which won’t last long and which can only cause harm, and that to me seems to be completely perverse."
