ELUSIVE GOAL FOR EARTH DAY 2000


It seemed daring at the time, even a little revolutionary. But then, revolutionary ideas were in vogue 30 years ago—along with tie-died clothes, the Beatles and Jimi Hendrix—when some 20 million Americans first came together to demand a cleaner environment. They called it "Earth Day."


Eye in the Sky


The year 2000 edition, which takes place around the world this weekend, finds the environmental movement bigger, better organized and more mainstream. But activists say they are still far from their goal of creating a sustainable human presence on the planet—especially by turning to non-polluting sources of energy in order to forestall global warming, the focus of this year’s event.

Global warming is "one of the most urgent environmental perils of our time," said Denis Hayes, who is reprising his role as national coordinator of the original Earth Day on April 22, 1970, by chairing this year’s event.

"The world’s leaders in Kyoto, Japan, in late 1997, acknowledged the scientific fact that the leading cause of global warming is carbon emissions from fossil fuel consumption, and that something must be done to address those rising emissions," said Hayes.

LITTLE PROGRESS ON TREATY

So far only 17 nations have ratified the global climate change treaty that grew out of the meeting. The pact calls for industrialized countries to sharply reduce their production of greenhouse gases resulting from use of fossil fuels such as coal and petroleum products.

Ratification by the U.S. Senate is seen as unlikely anytime soon, due to opposition from critics who say that developing countries like India and China should be held to similar standards.

While the political debate continues, more and more scientists are concluding that the current era of rising global temperatures is being caused at least in part by the burning of fossil fuels.

An early draft of a report now being developed by a blue-ribbon international scientific panel concludes that the rise in global temperatures over the past 150 years is "exceptional and unlikely to be solely natural in origin."

The Intergovernmental Panel on Climate Change—sponsored by the World Meteorological Organization and the United Nations—says that humans have "discernibly" influenced the climate and that surface temperatures are likely to rise between 2 and 9 degrees Fahrenheit (1-5 degrees Celsius) by the end of this century.

The consequences over the next few decades could be catastrophic, for example a relatively rapid rising sea level that could drown low-lying areas, including major coastal cities. The draft report estimates that the oceans could rise between 4 inches and 3 feet (10-90 centimeters).

To dramatize their message that the world should pay attention, Earth Day 2000 organizers on Saturday, April 22 are sponsoring hundreds of rallies, clean-energy demonstration projects and concerts in 181 countries. Major U.S. events will take place in Washington, Boston, Chicago and Los Angeles.

An all-day extravaganza dubbed EarthFair 2000 will held on the Mall near the U.S. Capitol. Movie mega-star Leonardo DiCaprio will introduce musicians James Taylor, Keb’ Mo’ and Third Eye Blind, and fellow actors Melanie Griffith and Chevy Chase.

TOUGH ACT TO FOLLOW

Earth Day 2000 has a tough act to follow. Organizers of the original 1970 version—originally conceived by then-U.S. Senator Gaylord Nelson (D) of Wisconsin, claim credit for massively increasing the level of environmental awareness among Americans, leading to creation of the U.S. Environmental Protection Agency and the passage of the Clean Air, Clean Water and Endangered Species acts.

The 1990 edition took a global perspective, with an estimated 200 million people in 141 countries rallying to put environmental issues on the world stage. In the United States this year’s Earth Day sponsors consist of 32 groups whose names are a who’s who of the environmental movement, from the Alliance to Save Energy to the World Wildlife Fund.

Organizers are making extensive use of a wonderful new device for coordinating activities around the world. And by the way, they point out, the Internet is non-polluting.

WHAT NELSON STARTED

Earth Day was founded in 1970 by Gaylord Nelson, then a U.S. senator from Wisconsin. He said his objective was "to organize a national demonstration of concern for the environment so large that it would shake up the political establishment and force this issue onto the national agenda. It was a gamble, but it worked."

The event successfully drew together for the first time a broad cross-section of Americans, including Republicans and Democrats, city and rural dwellers, rich and poor, labor and business interests, young and old.

By massively raising awareness, organizers claim credit for the creation of the U.S. Environmental Protection Agency and passage of major environmental legislation. Nelson was awarded the Presidential Medal of Freedom by President Clinton, who noted that he "inspired us to remember that the stewardship of our natural resources is the stewardship of the American dream."
