She goes on: "The planet will be OK in its own way. No matter what we do to it, we won't eliminate every last life form from it." As evidence of this, there's the Canadian city of Sudbury, a favourite of Atwood's. When she was growing up in the 1940s, the place was as "barren as the moon" through overlogging, forest fires and relentless mining. "All the rain was acid," she says. It was so bad that "a Sudbury" became a unit of pollution. But then a volunteer programme of regeneration was launched. Earth and seeds were painstakingly stuffed into the cracks between the rocks. Now, "Sudbury has forests again, birds in the trees and fish in the streams." For her, Sudbury, "a symbol of hope", offers a paradigm for the planet.
And so, Atwood continues, with rather bracing realism, "some form of life will remain after us. We shouldn't be saying 'Save the planet'; we should be saying: 'Save viable conditions in which people can live.' That's what we're dealing with here."
Atwood likes to tell the Amoeba's Tale as an illustration of the "magic moment" at which planet earth now finds itself. There's this test tube, and it's full of amoeba food. You put one amoeba in at 12 noon. The amoeba divides in two every minute. At 12 midnight the test tube is full of amoebas – and there's no food left. Question: at what moment in time is the tube half full? Answer: one minute to midnight. That's where we are apparently. That's when all the amoebas are saying: "We are fine. There's half a tube of food left."
"If you don't believe me," Atwood persists, "look at the proposed heat maps for 20, 30, 50 years from now, and see what's drying up. Quite a lot, actually, especially in the equatorial regions and the Middle East, which will be like a raisin. It's become a race against time and we are not doing well. The trouble with politicians [at events like the Copenhagen summit of 2009] is that no one wants to go first, go skinny dipping and take the plunge. Oh, and then you have people arguing about fatuous things like the environment and human rights. Go three days without water and you don't have any human right. Why? Because you're dead. Physics and chemistry are things you just can't negotiate with. These," she concludes with a kind of grim relish, "these are the laws of the physical world."
