We live on a planet - there’s just one of them.

We need to wake up to the fact that we don’t have any more, and this is a finite planet. We know the limits of the resources we have. We may be able to use them differently, we may have some innovative new ideas, but in general, this is what we’ve got - there is no more of it.

There’s a basic equation which we can’t get away from. Population times consumption has got to have some kind of relationship to the planet - and right now it’s simply not equal. Our works shows that we’re living at about 1.3 planets. Since 1990, we crossed the line of being in a sustainable relationship to the planet. If we were farmers, we’d be eating our seed, or bankers, we’d be living off the principle, not the interest.
