How serious are the threats to our environment? Here is one measure of the problem: if we continue to do exactly what we are doing, with no growth in the human population or the world economy, the world in the latter part of this century will be unfit to live in. Of course human activities are not holding at current levels—they are accelerating, dramatically—and so, too, is the pace of climate disruption, biotic impoverishment, and toxification.

On Earth Day 1970 20 million Americans displayed their commitment to a clean environment. It was called the largest demonstration in human history, and it permanently changed the nation's political agenda. By Earth Day 2000 participation had exploded to 500 million people in 167 countries. The seemingly simple idea—a day set aside to focus on protecting our natural environment—was the brainchild of U.S. Senator Gaylord Nelson of Wisconsin.

Humanity can make short work of the oceans' creatures. In 1741, hungry explorers discovered herds of Steller's sea cow in the Bering Strait, and in less than thirty years, the amiable beast had been harpooned into extinction. It's a classic story, but a key fact is often omitted. Bering Island was the last redoubt of a species that had been decimated by hunting and habitat loss years before the explorers set sail.

In humanity’s more than 100,000 year history, we have evolved from vulnerable creatures clawing sustenance from Earth to a sophisticated global society manipulating every inch of it. In short, we have become the dominant animal. Why, then, are we creating a world that threatens our own species? What can we do to change the current trajectory toward more climate change, increased famine, and epidemic disease?

In this brilliant portrait of the oceans' unlikely hero, H. Bruce Franklin shows how menhaden have shaped America's national-and natural-history, and why reckless overfishing now threatens their place in both.

One morning in 2000, Dr. Jane Hightower walked into her exam room to find a patient with disturbing symptoms she couldn’t explain. The woman was nauseated, tired, and had difficulty concentrating, but a litany of tests revealed no apparent cause. She was not alone. Dr. Hightower saw numerous patients with similar, inexplicable ailments, and eventually learned that there were many more around the nation and the world.

The media constantly bombard us with news of health hazards lurking in our everyday lives. But many of these hazards turn out to have been greatly overblown. According to author and epidemiologist Geoffrey C. Kabat, this hyping of low-level environmental hazards leads to needless anxiety and confusion on the part of the public as to which exposures have important effects on health and which are likely to have minimal or no effect.

Billy Sothern's Down in New Orleans illustrates, in very human and heartbreaking ways, how the horrors that emerged during and following Hurricane Katrina existed long before the storm. These beautifully composed stories not only reveal the dignity—and amazing grit and grace—of the hurricane's survivors; they also illuminate larger truths about the urgent issues of our day.

Inspired by the still-revolutionary theories of Rachel Carson's Silent Spring, James E. McWilliams argues for a more harmonious and rational approach to our relationship with insects, one that does not harm our environment and, consequently, ourselves along the way.

Already technology enables parents to select some genetic traits for their children, and soon it will be possible to begin to shape ourselves as a species. Countering loud cries of alarm, bioethics expert Ronald Green explains why our fears about genetic engineering are overblown and how we can move forward responsibly to create a better future.

The true story of a resilient circle of shrimp boat captains who faced and withstood the wreckage of Katrina but now find their courage tested by a greater threat: the disappearance of their livelihood and their centuries-old bayou culture.
