Editors' Summary: Pfiesteria piscicida, a sometimes toxic microorganism, is responsible for the death of millions of fish in Delaware, Maryland, North Carolina, and Virginia. Although the problem of Pfiesteria-related fish kills is associated with the Mid-Atlantic region, other toxic microorganisms have threatened fish and marine wildlife throughout the world. Scientists attribute this "global epidemic" of toxic microbes to excessive nutrient loading from nonpoint sources of pollution.

Water scarcity is no longer a threat, it is a reality. Increasing populations throughout the country and the world are putting increased pressure on existing supplies of freshwater. Cities, states, and regions are scrambling to find solutions to this burgeoning problem. The impact of drought, which has been felt not only in the typically dry Southwest, but also in the humid Southeast this past summer, compounds the problem. So, what mechanisms evolve to help alleviate the problem?

Above my desk at work, I keep a button that reads "Save the Ugly Animals Too." It is a reminder that more than just the charismatic megafauna, such as wolves and bald eagles and grizzly bears and whales, are worth conserving. From the standpoint of protecting the web of life, including the ecosystems that benefit us all by providing services such as water purification, flood control, nurseries for our fish and shellfish, and opportunities for outdoor recreation, it is often as important to conserve the lesser known species, the cogs and wheels that drive those ecosystems.

In a recent essay, Katrina Wyman suggests four substantial reforms aimed at improving implementation of the Endangered Species Act (ESA) and furthering species recovery: (1) decoupling listing decisions from permanent species protection;3 (2) requiring the Fish & Wildlife Service (FWS) to implement cost-effective species protection measures;5 (3) prioritizing funding for biological hotspots;6 and (4) establishing additional protected areas.

Katrina Wyman has penned a bold, provocative, and innovative critique of the capability of the Endangered Species Act (ESA or Act) to meet the challenges of an increasingly human-dominated world. Bold because the ESA, perhaps more than any other environmental law, has impassioned champions who disfavor dissent. It is no easy task to critique a law with the truly noble mission to preserve life other than our own, particularly when the law's basic premise is that the mission's success is critically dependent on abundant and altruistic actions by us.
