Gulf Oil Spill May Reach North Carolina Islands, Miami Beach
Crude from the massive Gulf of Mexico oil spill could eventually slosh ashore on Miami Beach or North Carolina’s barrier islands, if it connects with a powerful sea current, an oceanographer said Tuesday.
Robert Weisberg, a physical oceanographer at the University of South Florida, told a …

It was revealed last week that China is dealing with an explosive infestation of the formerly inconsequential mirid bug in its orchards and cotton fields. The bug’s population exploded as a result of widespread planting of cotton that had been genetically altered to be resistant to the bollworm, formerly cotton’s worst enemy. Cotton farmers stopped spraying insecticides, since their plants shrugged off the bollworms, and thus allowed other insects, especially the mirid bug, to multiply without interference.
Throughout the American heartland, farmers who were persuaded to stop cultivating, stop spraying more toxic weed sprays and give their faith to Roundup are being overcome by resurgent weeds. One of them, pigweed, is a mutant monster that can reach seven feet in height and can ruin a combine. The high costs of the modified seed, the increasing cost of applying more and more Roundup to less and less effect, added to the need to resume tilling and the use of older chemicals, adds up to “…the single largest threat to production agriculture that we have ever seen,” according to Andrew Wargo III, the president of the Arkansas Association of Conservation Districts.
Gulf Coast braces for another round of environmental devastation after deadly explosion triggers a massive oil leak
Above the oily Gulf waters, planes dropped more than 156,000 gal of dispersant into the slick. The proprietary chemical mix acts like soap and breaks down the oil on and below the surface into less harmful molecules. The dispersants have toxic qualities, says Thomas, “but we’ve got to get rid of this oil.”
The week of May 3, favorable winds were keeping most of the oil from reaching land; the estimated size of the oil sheet shrank, to 2,000 sq miles from 3,400 sq miles. The Mississippi’s flow is keeping the spill east of the river mouth, and some scientists worry that the farther south and east the oil moves, the more likely the spill could hit the Gulf Stream and make its way up the East Coast.
