" Unfortunately the hostility that the European displayed toward the native cultures he encountered he carried even further into his relations with the land. The immense open spaces of the American continents, with all their unexploited or thinly utilized resources, were treated as a challenge to unrelenting war, destruction, and conquest. The forests were there to be cut down, the prairie to be plowed up, the marshes to be filled, the wildlife to be killed for empty sport, even if not utilized for food or clothing.

In the act of 'conquering nature' our ancestors too often treated the earth as contemptuously and as brutally as they treated its original inhabitants, wiping out great animal species like the bison and the passenger pigeon, mining the soils instead of annually replenishing them, and even, in the present day, invading the last wilderness areas, precious just because they are still wildernesses, homes for wildlife and solitary human souls. Instead we are surrendering them to six-lane highways, gas stations, amusement parks, and the lumber interests, as in the redwood groves, or Yosemite, and Lake Tahoe-though these primeval areas, once desecrated, can never be fully restored or replaced.
