A Texas company quit plans to build a coal-fired power plant -- blaming President Obama's environmental rules, but admitting the low price of natural gas was a key reason.

Today the Supreme Court will hear arguments in a case testing the reach of GMO companies' market power based on intellectual property claims -- and while environment and health are not immediately before the court, a case that could have wide impacts on both.

"Are people exposed to doses of bisphenol A in their canned foods and other consumer products that can harm them? Or are the amounts too low to cause any harm? This is the crux of a vehement debate that is being waged as federal officials are trying to decide whether the chemical, known as BPA, should be regulated."

"BOSTON -- Exposure to lead—so toxic—is a problem of the past, right? Wrong. Since the U.S. took lead out of gasoline in 1976 and banned lead paint in 1978, most health scientists, regulators and the public have considered the problem largely solved. But ongoing testing shows that even though the average concentration of lead in the American bloodstream has dropped by a factor of 10 since the late 1970s, the levels are still two orders of magnitude higher than natural human levels, which have been determined by studying skeletal remains of native Americans dating to before the industrial revolution."

"The agricultural giant Monsanto has sued hundreds of small farmers in the United States in recent years in attempts to protect its patent rights on genetically engineered seeds that it produces and sells, a new report said on Tuesday."

EPA scientists in 2010 were ready to declare that even small amounts of hexavalent chromium -- found in the drinking water of some 70 million Americans -- may cause cancer. But the American Chemistry Council, the main industry lobby group, urged delay. EPA did delay, on the recommendation of a science panel that was supposed to be independent -- but was secretly stacked with panelists tied to the industry. In fact, they had helped industry oppose hexavalent chromium lawsuits instigated by Erin Brocovich.
