1. Historical Overview of the Modern Environmental Movement

2. In the beginning… ~10,000 years ago the human population began to rise after the Neolithic Agricultural Revolution. –Humans settled to become farmers instead of local hunter-gatherers. –This meant managing local resources (food, water, fuel) sustainably around the settlement

13. The Green Revolution 1940s – 1960s Modern agriculture boosted food production significantly. Required machinery and tremendous amounts of fossil fuel. New crops varieties were developed and fertilizer and pesticide use rose sharply. World population grew to about 3 billion.

14. Aldo Leopold Wrote A Sand County Almanac in 1949. Widely considered the most important environmental book ever written. Argues that we have an ethical responsibility to be good stewards of the land.
