...years since then, the strongman has grown more reclusive and his country more xenophobic -- and poorer. Per capita income stands at only $200 a year, well below that of China and the Philippines. Once the major rice exporter of South Asia, Burma is now barely self-sufficient in that staple. Rangoon is a seedy, decaying city where paint peels on once grand Victorian mansions; a Western visitor to the capital last week found that little had changed in the past five or six years...
Buried toxins can also be moved around by shrimp and other creatures that dig into the bottom and spread the substances through digestion and excretion. Though ocean sediment generally accumulates at a rate of about one-half inch - per thousand years, Biogeochemist John Farrington of the University of Massachusetts at Boston cites discoveries of plutonium from thermonuclear test blasts in the 1950s and 1960s located 12 in. to 20 in. deep in ocean sediment. Thus contaminants can conceivably lie undisturbed in the oceans indefinitely -- or resurface at any time...
...land and the installation and inspection of septic tanks. Farmers are now required to fence cattle away from streams. Zoning has become more stringent for construction in a critical watershed area: a single-family house requires at least two acres of land. The number of livestock and poultry per acre is also controlled...
...solution, many scientists believe, is to impart artificial gravity -- in the form of centrifugal force -- to the spacecraft. This might be accomplished by spinning a very large craft around its own axis. Other schemes envision three ships hooked together in a cartwheel-like arrangement that makes three revolutions per minute, or two vehicles attached by a half-mile-long tether rotating through space as the entire system speeds toward Mars. Still another idea is to schedule a daily workout for each crew member inside an on-board centrifuge, where resisting the centrifugal force would simulate working in gravity...
