Historical Overview of the Modern
Environmental Movement
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
Industrial Revolution
• Began in the early 1800s
• Produced goods and services for nearly all, but demanded the burning of large amounts of trees and coal.
• Required large-scale mining.
• Land was cleared, natural waterways were polluted, cities became crowded and smoky.
James Fenimore Cooper
• 1820s• Wrote Last of the
Mohicans, The Pioneers, and The Prairie.

• Nature must be preserved for future generations.
• Pollution and other activities endanger life on Earth.

• Likely caused by a combination of poor farming practices and a severe drought.
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.
Aldo Leopold
