I wanted to send along this video:
I caught this report Natural gas might not be what it’s fracked up to be, (By Eve Troeh, Marketplace, Tuesday, April 12, 2011), which talks about a new study that shows that the mining of natural gas may let off more greenhouse gases than just using coal. For quite a while, natural gas has been promoted as a cleaner fuel, but the extraction of natural gas complicates its use.
From PBS News Hour: “The Supreme Court heard arguments Tuesday stemming from a 2004 lawsuit over whether the Environmental Protection Agency has the authority to regulate greenhouse gas emissions. Gwen Ifill speaks with the National Law Journal’s Marcia Coyle about the case, the arguments and the justices’ reactions.”

Wanted to send along this link: How Western Diets Are Making The World SickHere’s a description:
In a conversation on Fresh Air, [physician Kevin] Patterson tells Terry Gross that the effects of urbanization are making people everywhere in the world both fatter and sicker.”Type 2 diabetes historically didn’t exist, only 70 or 80 years ago,” says Patterson. “And what’s driven it, of course, is this rise in obesity, especially the accumulation of abdominal fat. That fat induces changes in our receptors that cells have for insulin. Basically, it makes them numb to the effect of insulin.”For a long time, the human body can compensate — the pancreas secretes even larger amounts of insulin, which regulates blood sugar levels. But over time, the pancreas begins to fail to secrete enough insulin, and that is when diabetes develops.He explains that the increase in abdominal fat has driven the epidemic of diabetes over the last 40 years in the developed world — and that he’s now seeing similar patterns in undeveloped regions that have adapted Western eating patterns.
