Environmental Failure: A Ruined Planet Is Closer to Reality

A specter is haunting American environmentalism -- the specter of failure.

All of us who have been part of the environmental movement in the United States must now face up to a deeply troubling paradox: Our environmental organizations have grown in strength and sophistication, but the environment has continued to go downhill, to the point that the prospect of a ruined planet is now very real. How could this have happened?

Before addressing this question and what can be done to correct it, two points must be made. First, one shudders to think what the world would look like today without the efforts of environmental groups and their hard-won victories in recent decades. Listen: James Gustave Speth talks with Yale e360 about building a new environmentalism. (27 min.) However serious our environmental challenges, they would be much more so had not these people taken a stand in countless ways. And second, despite their limitations, the approaches of modern-day environmentalism remain essential: Right now, they are the tools readily at hand with which to address many pressing problems, including global warming and climate disruption. Despite the critique of American environmentalism that follows, these points remain valid.

Lost Ground

The need for appraisal would not be so urgent if environmental conditions were not so dire. The mounting threats point to an emerging environmental tragedy of unprecedented proportions.

Half the world's tropical and temperate forests are now gone. The rate of deforestation in the tropics continues at about an acre a second, and has for decades. Half the planet's wetlands are gone. An estimated 90 percent of the large predator fish are gone, and 75 percent of marine fisheries are now overfished or fished to capacity. Almost half of the corals are gone or are seriously threatened. Species are disappearing at rates about 1,000 times faster than normal. The planet has not seen such a spasm of extinction in 65 million years, since the dinosaurs disappeared. Desertification claims a Nebraska-sized area of productive capacity each year globally. Persistent toxic chemicals can now be found by the dozens in essentially each and every one of us.

The earth's stratospheric ozone layer was severely depleted before its loss was discovered. Human activities have pushed atmospheric carbon dioxide up by more than a third and have started in earnest the most dangerous change of all -- planetary warming and climate disruption. Everywhere, earth's ice fields are melting. Industrial processes are fixing nitrogen, making it biologically active, at a rate equal to nature's; one result is the development of hundreds of documented dead zones in the oceans due to overfertilization. Freshwater withdrawals are now over half of accessible runoff, and water shortages are multiplying here and abroad.

The United States, of course, is deeply complicit in these global trends, including our responsibility for about 30 percent of the carbon dioxide added thus far to the atmosphere. But even within the United States itself, four decades of environmental effort have not stemmed the tide of environmental decline. The country is losing 6,000 acres of open space every day, and 100,000 acres of wetlands every year. About a third of U.S. plant and animal species are threatened with extinction. Half of U.S. lakes and a third of its rivers still fail to meet the standards that by law should have been met by 1983. And we have done little to curb our wasteful energy habits or our huge population growth.

Here is one measure of the problem: All we have to do to destroy the planet's climate and biota and leave a ruined world to our children and grandchildren is to keep doing exactly what we are doing today, with no growth in human population or the world economy. Just continue to generate greenhouse gases at current rates, just continue to impoverish ecosystems and release toxic chemicals at current rates, and the world in the latter part of this century won't be fit to live in. But human activities are not holding at current levels -- they are accelerating, dramatically.
