We can no longer prosper by increasing human productivity. The more we try to do, the more poverty we will create.

We have an economy that tells us it is cheaper to destroy earth in real time rather than renew, restore, and sustain it. You can print money to bail out a bank but you can't print life to bail out a planet.
