...meeting of the Geological Society of America. Geologists have known for centuries that a swath of central India was buried by a series of eruptions at around the time of the dinosaurs' demise. The remains of the flows, known as the Deccan Traps, still cover some 193,000 sq. mi. (500,000 sq km). The eruptions would have poured carbon dioxide and sulfur dioxide into the air, triggering runaway global warming and acid rain. That's bad news for living things, but it has never been clear if the eruptions were sufficiently well timed to cause the extinctions...
Green roofs are by no means limited to the city, but it's in cities that they're needed the most. Chicago already has more than 2.3 million sq. ft. (214,000 sq m) of rooftops planted, and more are on the way. Other rapidly greening U.S. cities include Washington; New York City; Phoenix; Kansas City, Mo.; and Portland...
...them are enthusiastic proselytizers for their neo-nomadic lifestyle. "This is the ideal American subculture; it's the way everyone would like it to be," says Howard Payne, a real estate lawyer who, along with his wife Linda, traded a five-bedroom house in Louisville, Ky., for a 400-sq.-ft. (37 sq m) motor home in August...
...while inflating the rents of the little guys. Ebberson's neighbor Mike Korth has a 1,000-acre (400 hectare) corn and soybean spread that would have been considered enormous a century ago but is now about average for the area. His township has only 39 families on 36 sq. mi. (94 sq km), a frontier-level population density. No wonder a Federal Reserve Bank of Kansas City study found the rural counties most dependent on subsidies had the worst population losses and the weakest job growth...
...conservation payments for eco-sensitive farmers of any size. The results would be less erosion; more restoration of grasslands and wetlands; and less degradation of water bodies like the Chesapeake Bay, the Everglades, the Colorado River and the Gulf of Mexico, where farm nutrients have created a 5,000-sq.-mi. (13,000 sq km) dead zone...
