Nature is out there, and we can do what we like to it. We can cut down the rain forest. We can put animals in factory farms and slaughter them as we like. We can over-fish the oceans. We can pollute the rivers. We can pollute the water and change climate. We are somehow superior to nature. We are somehow rulers of nature.

People are increasingly becoming disappointed and disillusioned with politics and business, and especially with the market economy. They are meeting the physical needs of human beings, maybe. They are providing food. But not good and healthy food.

Look at what realists have done for us. They have led us to war and climate change, poverty on an unimaginable scale, and wholesale ecological destruction. Half of humanity goes to bed hungry because of all the realistic leaders in the world. I tell people who call me 'unrealistic' to show me what their realism has done. Realism is an outdated, overplayed and wholly exaggerated concept.

We need to develop a sense of sufficiency to be happy.
