What I'm saying so badly is we're bred now to believe we're in control and should be in control.

I don't believe there's anything cosmic or divine or morally superior about whales and dolphins or sharks or trees, but I do think that everything that lives is holy and somehow integrated; and on cloudy days I suspect that these extraordinary phenomena, and the hundreds of tiny, modest versions no one hears about, are an ocean, an earth, a Creator, something shaking us by the collar, demanding our attention, our fear, our vigilance, our respect, our help.

We rise to a challenge and set a course. We take a decision. You put your mind to something. Just deciding to do it gets you halfway there. Daring to try.

It's terrifying to think you can remember things you shouldn't possibly be able to. It's like that childhood fear of having your soul slip from your body in your sleep. The darkness, those black sheets of glass sliding over you, upping the pressure, pushing you through the time and space and story.

People do change - individuals, families, nations - and the pace of transformation need not be geological.

Australia was once a leader in taking global warming seriously. The former PM [Kevin Rudd] called it 'greatest moral challenge of our time'. But in the past couple of years the national consensus has been eroded and Australians are being encouraged by the polluters and their mates in Parliament to forget it was ever mentioned. It's heartbreaking.

Ah, but you, Darkness, you know all this. I tell you night after night. Nothing will shock you. Maybe I go on at you in the hope that there's something beyond you. Some nights I sit here and talk and sob and stare out into the blackness thinking that if I look hard enough I'll see the light behind. But I stay out until the break of day, waiting, hoping, and there's only sunrise again.
