On this 40th anniversary of Earth Day, prepare to be bombarded with apocalyptic tales of disaster. But don't let the gloom-and-doom-fest get you down. Odds are the doomsters will be wrong.
To help "celebrate" the first Earth Day in 1970, biologist Barry Commoner wrote, "We are in an environmental crisis which threatens the survival of this nation, and of the world as a suitable place of human habitation."
In a speech at Swarthmore College that year, ecologist Kenneth Watt said, "If present trends continue, the world will be about 4 degrees colder for the global mean temperature in 1990, but 11 degrees colder in the year 2000. This is about twice what it would take to put us into an ice age." And a New York Times editorial proclaimed: "Man must stop pollution and conserve his resources, not merely to enhance existence but to save the race from intolerable deterioration and possible extinction."
