Conventional economics is a form of brain damage.

Scientists have been warning about global warming for decades. It's too late to stop it now, but we can lessen its severity and impacts.

And that, quite simply, is the issue. We live in a finite world with finite resources. Although it may sometimes seem quite big, earth is really very small - a tiny blue and green oasis of life in a cold universe.

You would have thought that our first priority would be to ask what the ecologists are finding out, because we have to live within the conditions and principles they define. Instead, we've elevated the economy above ecology.
