bias—that is, its attempt to stop incipient problems before they become acute and require institutionalized responses.

Experiments in protecting biodiversity find sturdy underpinnings in a growing library of scholarship on the subject and in an expanding number of students learning the principles of conservation biology and landscape ecology. In addition to E.O. Wilson's volumes, the library now includes significant contributions from a wide range of experts, many of whom can be sampled in Landscape Linkages and Biodiversity, published in 1991 by Defenders of Wildlife. A comprehensive textbook, Landscape Ecology by Richard T.T. Forman and Michel Godron, has been available since 1986. Biodiversity experts have also formed the International Association for Landscape Ecology. Followers of this discipline perform "gap analyses” to generate digital maps that identify both species-rich areas and other ecosystems inadequately protected by existing reserves.

As the frog massacre on the British motorway demonstrates, many species—not just those officially inscribed as endangered species—are now extremely vulnerable. They are at risk from depletion of stratospheric ozone, enormous growth in human populations and economic activity, global warming, droughts, fires, pollution, disease, and other environmental shocks. British authorities, realizing that biological systems require margins of safety, finally tunneled under the motorway to reconstitute the ancient "frogway."

Great Water Bodies at a Watershed

Pollution prevention and
a regional approach are needed

deteriorate without controls on nonpoint sources of pollution in the watershed.

Today, the Chesapeake Bay region is undertaking the critical transition from "end of the pipe" controls to a watershed approach that embraces all the impacts that converge on a water body. Prompted by pressure from the Chesapeake Bay Foundation and other citizen groups, the governments of Pennsylvania, Maryland, Virginia, and

Chesapeake Bay Drainage Area

ou might not think that two Pennsylvania farmers could help

watermen in the Chesapeake Bay harvest more shellfish. But Joe and David Garber, by carefully applying fertilizer to their Spring Lawn Farm, are helping to demonstrate how we can achieve sustainable use of our great water bodies.

The goal of sustainable use is critical. From generation to generation, our bays and coastal waters have provided an economy and a way of life for millions of people. They have helped to enrich our lives and to define the communities in which we live. Who can imagine a Baltimore without Chesapeake Bay, a Seattle without Puget Sound, a Chicago without Lake Michigan?

However, when we use our great water bodies as cheap all-purpose dumps, we can wind up with shellfish quarantines, seafood health advisories, and closed summer beaches. Nationwide, there are 2,100 health advisories for fish contaminated by toxic chemicals, according to a 1991 National Academy of Sciences report, Seafood Safety. Overfishing,

development, and pollution threaten "to destroy the harvest of wild shellfish ... throughout the nation's coastal areas," according to a 1990 report by the National Oceanic and Atmospheric Administration. Salmon runs in California and the Pacific Northwest are in serious decline as upstream dams and canals divert river flows. Our great water bodies can become, in the words of the accountants, “non-performing assets."

To keep our great water bodies fit to perform, we have invested funds in the last two decades to clean up discharges from our sewage treatment plants. However, as the Chesapeake Bay region has learned, controlling pollution at the "end of the pipe" is not enough to ensure the goal of sustainable use. Progress in cleaning up sewage discharges has been offset by the occurrence of slimy algal blooms in the bay. These dense, greenish blooms cut off light to critical seagrass beds or submerged aquatic vegetation. The blooms, as they decay, deplete lifegiving dissolved oxygen for finfish. Nutrient-rich loads of nitrogen and phosphorous feed these destructive blooms. Phosphate detergent bans and nutrient removal in sewage plants will not suffice to roll back these destructive blooms, which are nurtured by livestock wastes and farm fertilizers from the vast bay watershed. More than a decade ago, scientists warned that the bay would continue to

the District of Columbia, in partnership with EPA, signed an agreement in 1987 to cut nutrient loads to the bay by 40 percent by the year 2000. Pennsylvania provides technical and financial aid to farmers like the Garbers who develop nutrient management plans to minimize runoff of manure and artificial fertilizers.

Maryland is working to enlist virtually every citizen in the bay cleanup. To help reduce soil erosion to the bay, thousands of Marylanders planted 1.4 million trees during Earth Month in 1991. To help companies reduce toxic discharges to the bay, the state sponsors special workshops on how to change to environmentally compatible manufacturing processes. To help fund such efforts, more than 300,000 citizens bought special “Treasure the Chesapeake” vehicle license plates.

Is the bay saved? Hardly. Its worldfamous oyster population is seriously depleted. Nitrogen levels remain too high. Phosphorous levels are dropping and some seagrass beds are recovering, but even this progress may be offset if another impact converging on our coastal regions is not controlled. The bay watershed population will grow 20 percent by 2020, and a recent report notes "unmanaged new growth has the potential to erase any progress made in bay improvements, overwhelming past

An Urgent Agenda

Nongovernmental organizations must reexamine programs and priorities

by John Adams

a

he United Nations Conference on Environment and Development in

Rio last June changed history. For those of us in public interest groups who work for environmental protection in the United States, it changed the entire context of our work and it changed fundamental ground rules.

Sustainable development is an ideal that many of us have cherished for very long time. Now that the largest gathering of heads of state in history has confirmed a need that we saw all along, it would be easy for us simply to congratulate ourselves. But Rio is far from being merely a cause for celebration. It also conferred responsibility-the responsibility to live up to ideals that we ourselves promoted, and the responsibility to make sure this new international agreement becomes a real commitment instead of only words on paper.

Rio set a new standard by which the work of U.S. environmental organizations should be measured. We must all reexamine our programs and priorities in light of the ideals of Rio and ask whether we are in fact doing our utmost to achieve a sustainable society in this country.

First, there is choice of priorities. Rio deliberate program focused on creating forces us to ask hard questions. Are we a sustainable society, we cannot claim in fact devoting our resources to the to be meeting the standard we primary problems obstructing
