About one-quarter of the United States' land cover, excluding Alaska, is farmed—some 430 million to 500 million acres. A massive new project has just assessed this and other food-producing environments, such as coastal waters, fresh waters, and rangelands, to tally factors contributing to health. Released on Sept. 24, it indicates that most ecosystems are undergoing change—some declining dramatically while others improve.In 1995, the White House Office of Science and Technology Policy commissioned the H. John Heinz Center for Science, Economics and the Environment to launch a nonpartisan, scie...Published: Wednesday, September 25th, 2002Found in: Ecology -
Home / Blogs / Food for Thought / Food for Thought : No Way to Make SoupThirty-two tons of contraband shark fins seized on the high seasSomething looked suspicious.On Aug. 13, a helicopter from the Navy's USS Fife spotted an 84-foot fishing boat—the King Diamond II out of Honolulu—plowing slowly through international seas southeast of Acapulco, Mexico. Riding low in the water, the modern vessel appeared weighted down with heavy cargo. Yet there were no signs of fishing gear. Particularly curious, on its deck was a shipping container like those ferried by long-haul trucks or container ships.When the crew radioed in the sighting, a Coast Guard law-enforcement detachment on the Fife agreed that something didn't sound quite right....Published: Wednesday, September 4th, 2002Found in: Ecology
