Daniel Quinn's Theory of Leavers and Takers

I have recently finished two of Daniel Quinn's Novels, titled "Ishmael" and "The Story of B". In both novels he exposed me to his theory of how everything came to be. I will do my best to explain his theory succinctly:

Man in his current form (homo sapiens sapiens) first came to be 3 million years ago. For 3 million years man lived on the earth in an environmentally friendly way, and evolved social systems that worked well and continue working well up into the present day. Some were hunter-gatherers, and some were agriculturalists, but all of them participated in cultures that minimized destruction of other species and limited their own population growth. About 10,000 years ago, in various parts of the world a group of man participated in a new culture whose basis was totalitarian agriculture, which is the agriculture we use today. This process makes a piece of land exclusively to the benefit of man, and as a result greatly increases food production. Increase in food production leads to increase in population, which then requires an increase in land appropriation for increased food production etc. This process started 10,000 years ago has led to our current situation, with a skyrocketing human population in the world and all of the environmental and social impacts that a high population yields.

It is Daniel Quinn's opinion that almost all the negative aspects of today's modern society is due to the abandonment of time-tested tribal culture and the embracing of agricultural overproduction which has led to overpopulation. These problems such as war, famine, plague, and even modern apathy and depression are due to people living in an environment they were not evolved in or for. His solution is hazy, but it involves the limiting of population growth through the gradual limiting of food production, as well as a mental paradigm shift away from the current cultural attitudes.
