March 22, 2013 There's some evidence that carbon dioxide we pump into the atmosphere has slowed the development of coral reefs. So researchers are adding antacid to the water in a tiny part of the Great Barrier Reef, to see whether the corals will grow faster if their water supply is less acidic.
March 21, 2013 Congress on Thursday approved stopgap funding legislation that includes language explicitly granting the USDA authority to override a judge's ruling against genetically modified crops. Critics denounce the measure as the "Monsanto Protection Act." But it seems to be codifying powers the USDA already has exercised in the past.

But some environmental groups are skeptical about the effort because the standards are voluntary.
March 20, 2013 The giant sinkhole is threatening a neighborhood in southern Louisiana. A salt mine collapsed last year, creating a series of problems regulators say they've never seen before, including tremors and oil and gas leaks and a sinkhole that covers 9 acres. Residents are losing patience.
March 20, 2013 Seaweed might not be as flashy as coral, but it plays an important role on the reef. They compete for space, and rising carbon dioxide levels could someday tip the balance of power.
March 19, 2013 The new plant is expected to generate 100 megawatts of power and supply 20,000 homes with electricity.
March 19, 2013 The tropical island set in turquoise water just off the Great Barrier Reef is the site of an experiment to see what will happen to coral reefs as the ocean absorbs ever more of the carbon dioxide and heat we've added to our planet's thin skin. The results weren't so pretty.
March 18, 2013 Over the past three decades, the U.N. says Afghanistan's forest cover has decreased by about 50 percent — to just about 2 percent of the country's land. The main reason is the illegal harvesting and trade of timber. A visit to Kunar province, near the Pakistan border, reveals that many people, from top officials down, are involved.
March 14, 2013 The orange-and-black butterflies that winter in massive numbers in central Mexico each year have declined precipitously since a census count began 20 years ago.
March 12, 2013 WNYCUnder pressure from the New York state comptroller — who oversees one of its largest shareholders — the doughnut chain has agreed to set a goal of using only 100 percent sustainable palm oil to make its doughnuts. Production of palm oil has caused serious deforestation in Indonesia.
