Perhaps the longest-lasting impact of Hurricane Katrina was its environmental damage that, in real terms, has mainly to do with public health. Significant amounts of industrial waste and raw sewage spilled directly into New Orleans neighborhoods. And oil spills from offshore rigs
One positive result of the 1970s energy crisis was the development and widespread adoption of improved insulation materials to maintain indoor energy efficiency. Unfortunately, however, many of these materials have compromised indoor air quality due to their tendency to “off-gas” various airborne toxins, including formaldehyde, trichloroethylene (TCE), benzene and other volatile organic compounds (VOCs).

Most scientists and environmental experts view livestock grazing as an ecological disaster. For starters, cows and sheep are indiscriminate eaters and tend to remove every piece of grass and shrub in sight, thus eliminating shelter and food for birds and other wildlife
“Body Burden,” a 2005 study by the non-profit Environmental Working Group (EWG), found that American babies are born with hundreds of chemical contaminants in their bloodstreams. The findings are based on tests of samples of umbilical-cord blood taken by the American Red Cross from 10 babies,
An increasing number of public transit options are coming online throughout North America, but those of you idling alone bumper-to-bumper in your cars might not know it. Indeed, lack of knowledge about public transportation options may be the largest impediment to widespread acceptance of more efficient ways of getting around
Whether or not to allow the hunting of bison (also known as buffalo) is a hot debate indeed. For starters, Native Americans sustainably hunted bison for thousands of years, but the onslaught of gun-toting European commercial hunters reduced the species to just 30 remaining
