Crippling Blow. As if dehydration were not enough, the park ecosystem is now threatened by plans for an airport six miles from its northern border. Conservationists fear the effects of jet noise, exhaust fallout, fuel and oil spills. They also shudder at the prospect of helter-skelter development around the airport resulting in pollution from sewage, insecticides and fertilizer runoff...
...such worried conversation since James Baldwin forecast the fire next time. Suburban matrons predict the melting of the polar icecaps followed by catastrophic floods. Busy executives and bearded hippies discuss the presence of DDT in the flesh of Antarctic penguins. All sorts of Americans utter new words like ecosystem and eutrophication. Pollution may soon replace the Viet Nam war as the nation's major issue of protest...
Thoughtful gardeners should choose the least toxic control available; if it is a poison, they should buy the smallest quantity necessary. Above all, says Cry California, swear off DDT and other chlorinated hydrocarbons. The ecosystem you save will be your...
Almost 10% of the wildlife on the tiny raised atoll of Aldabra, 400 miles east of Africa, can be found nowhere else on earth. Owing to its isolation, Al-dabra's ecosystem has remained unique. Soaring with 7-ft. wingspreads at altitudes of more than half a mile, hundreds of thousands of frigate birds, which use Aldabra as their major Indian Ocean nesting site, blot out the rays of the sun. Thousands of rare giant land tortoises, some 4-ft. across and weighing as much as 600 Ibs., creep across the pitted coral and ridged limestone surface...
...establish an airstrip on Aldabra would require dredging and damming the atoll's 18-mile-long lagoon, creating a harbor and building a 13-mile causeway from the harbor to the airstrip. Such an invasion of bulldozers, concrete mixers and men, said the scientists, would irreversibly damage the ecosystem of the island. They added that the frigate birds would constitute one of the worst aircraft-collision haz ards in the world. The frigate is a sea bird that spends its adolescent years far from the island, returning to mate only after it is mature. Each year, a new crop...
