I’m increasingly attracted by the idea that there can be at least small pockets where life and character and beauty and meaning continue. If I could help protect one of those from destruction, maybe that would be enough. Maybe it would be more than most people do.

What does interest me is how difficult my culture seems to find it to look the dark side of life directly in the eye. It seems to me that if we look back at mediaeval culture, for example, we see a society which faces the reality of death and pain and limitation, because it has to. Our society, which is progressive and technological and seems to have a slightly fanatical utopian edge to it, gets very uncomfortable when anybody highlights the dark side of humanity, or the world we have built, or what we are doing to the rest of life on Earth.

In most novels, the landscape, or the place, in which the story takes part is simply a backdrop to the human action.

We like to think that the fate of the Earth and the fate of human worlds are the same thing, but we're not as important as that.

The mountains and moors, the wild uplands, are to be staked out like vampires in the sun, their chests pierced with rows of five-hundred-foot wind turbines and associated access roads, masts, pylons, and wires.

We enjoy telling ourselves that we will soon be gods, masters of the planet, manipulating the genes of living creatures and rebuilding the world at a nano-level as we lie back in our hammocks, attended by our robot servants. I don't believe a word of it, and I'm not sure many of us do.

It's always hard for an author to determine his own intentions, especially in retrospect.
