...Shade-grown coffee is exactly what it says. Instead of clearing the forest, farmers plant the crop among the forest plants, thus saving the local ecosystem. Shade trees furnish habitats for birds, and the Atlanta Audubon Society has found that 90% fewer species are found in sun-grown coffee areas. Shade trees also protect coffee plants from harsh elements, and the birds that are attracted provide natural pest control, which reduces the need for synthetic pesticides. As a bonus, many coffee drinkers find shade-grown varieties less bitter than those grown...
...America's farmlands, $4.5 billion in tax credits for renewable-energy technology, and a proposal to create the first new wilderness area in more than a decade. You also failed to examine the reasons for the President's Healthy Forests Initiative: the pressing need to prevent life-threatening, ecosystem-destroying, catastrophic fires by restoring the ecological health of our forests. JAMES L. CONNAUGHTON, CHAIRMAN WHITE HOUSE COUNCIL ON ENVIRONMENTAL QUALITY Washington
...that G.M. foods are necessarily a bad thing. In fact, I hope that Europe is being too cautious with their draconian labelling and fear of frankenfoods. These space-age crops have the potential to end famine, cure endemic nutritional diseases and even reduce ecosystem damage caused by pesticide use. But without more rigorous testing and additional research we simply do not know enough about them. U.S. companies have not yet earned the right to impose genetically modified foods on other countries or the U.S. public itself...
ENDANGERED ECOSYSTEM Currents and winds have carried the slick through coastal fishing grounds and across nearly 200 miles of shoreline. The sludge has coated hundreds of seabirds and closed local fisheries. Now other areas are threatened: shellfish beds and a nature preserve for marine birds, including the near extinct Iberian guillemot...
...friendly scale, bivalves generally rate highest among the more than 220 species of fish and shellfish that are cultivated commercially. Mussels and oysters are filter-feeders that make the surrounding water cleaner, so small-scale farming of them is not usually harmful to the ecosystem. Farming of crayfish in China--the largest supplier to the U.S.--is a relatively low-maintenance, drug-free business carried out in rice paddies. Next come the vegetarian freshwater species that do not need large quantities of fish meal--carp, catfish and tilapia. At the bottom are salmon and shrimp, onetime luxury foods that, thanks...
