...questions about the origins of non-De Beers diamonds. And that's a sound business decision, in light of the fact that the South African company has seen its market share drop precipitously in recent years, as competition from Russia intensifies. The company also announced Wednesday that it will flood the market with some of the millions of diamonds it has traditionally hoarded to keep prices high, suggesting that De Beers is hurting. Throwing open the vaults may bring prices down in the short term, but it could hurt the competition a lot more than the industry giant...
...flood of Biblical proportions were to lay waste to New Orleans, Joe Suhayda has a good idea how it would happen. A Category 5 hurricane would come barreling out of the Gulf of Mexico. It would cause Lake Pontchartrain, north of New Orleans, to overflow, pouring down millions of gallons of water on the city. Then things would really get ugly. Evacuation routes would be blocked. Buildings would collapse. Chemicals and hazardous waste would dissolve, turning the floodwaters into a lethal soup. In the end, what was left of the city might not be worth saving. "There's concern...
What is threatening New Orleans is a combination of two man-made problems: more levees and fewer wetlands. The levees installed along the Mississippi to protect the city from water surges have had a perverse effect: they have actually made it more vulnerable to flooding. That's because New Orleans has been kept in place by the precarious balance of two opposing forces. Because the city is constructed on 100 feet of soft silt, sand and clay, it naturally "subsides," or sinks, several feet a century. Historically, that subsidence has been counteracted by sedimentation: new silt, sand and clay that...
...environmentalists and engineers are frantically coming up with plans to save New Orleans. One idea is to raise levee walls to increase their effectiveness against storm surges. Another is to create large-scale diversions that would allow the Mississippi to flood in a controlled manner--and through sedimentation add thousands of acres a year of new land. Yet another would be to take immediate steps to reverse the loss of sensitive wetlands. Adding land through sedimentation is one of the best ways of restoring wetlands. Among other possible schemes: cutting back on shipping routes that harm marshes, installing wave absorbers...
Nature loves the rhythm of a meandering river, with the summertime droughts and spring floods that nurture wildlife and push a waterway down a new path. Commercial barges, however, demand constancy, in the form of a canal filled with enough water to keep their 9-ft.-deep hulls from running aground. So after the great 1927 flood, the Army Corps of Engineers began shackling the unruly current. The corps built levees along the river's banks to hold in the water and turned its rapids and ever changing sandbars into a more civilized staircase of 29 locks and dams stretching...
