What is Earth Day?

Earth Day, April 22, is the annual U.S. celebration of the environment and a time for Americans to assess the work still needed to protect the natural gifts of our planet. Earth Day has no central organizing force behind it, though several nongovernmental organizations work to keep track of the thousands of local events in schools and parks that mark the day. It affirms that environmental awareness is part of the country's consciousness and that the idea of protecting the environment -- once the province of a few conservationists -- has moved from the extreme to the mainstream of American thought.

This was not always the case. In the 19th century, Americans, blessed with a vast land rich in natural resources, lived with the notion that fresh fields were always just over the horizon. When one exhausted the soil or forests or coal of a given place, it was possible to move on to another. As industry boomed in the early 20th century people accepted without question skies blackened from smokestack emissions and rivers fouled with industrial waste. As early as the mid-1930s -- and again in the 1950s -- Ohio's Cuyahoga River, running through America's industrial heartland, was set ablaze by burning chemical waste from factories built upon its banks. There was no public outcry. Few people even noticed.
