James Lovelock: So should we be trying to save the world? “Don’t try and save the world, its pure hubris. We might be able to save Dorset. I think it’s easier to save Dorset than the planet. “There’s one thing to keep in mind here. We don’t need to save the planet, it’s looked after itself for four billion years. It’s always been habitable and things have lived on it, so why worry.” At the end of the day, “It pays to be cheerful,” he says.
