In September of 2003, Michael Crichton gave a speech to the Commonwealth Club in San Francisco. In it he attacked the modern environmentalist movement.
And what about indigenous peoples, living in a state of harmony with the Eden-like environment? Well, they never did. On this continent, the newly arrived people who crossed the land bridge almost immediately set about wiping out hundreds of species of large animals, and they did this several thousand years before the white man showed up, to accelerate the process. And what was the condition of life? Loving, peaceful, harmonious? Hardly: the early peoples of the New World lived in a state of constant warfare. Generations of hatred, tribal hatreds, constant battles. The warlike tribes of this continent are famous: the Comanche, Sioux, Apache, Mohawk, Aztecs, Toltec, Incas. Some of them practiced infanticide, and human sacrifice. And those tribes that were not fiercely warlike were exterminated, or learned to build their villages high in the cliffs to attain some measure of safety.
He goes on to compare environmentalism to religion. And they match up quite nicely. If you consider yourself an environmentalist, please take a second and read this. And everyone else should read it to. Another example of a good thing taken too far.
