The “greenhouse effect” often gets a bad rap because of its association with global warming, but the truth is we couldn’t live without it.

Bush Wants to Squeeze Oil from Stone

Tuesday July 22, 2008
Reacting to voter anger over $4-per-gallon gasoline and growing concerns about U.S. dependency on foreign oil, the Bush administration is floating the idea of extracting petroleum from oil-shale deposits in the Western United States that could eventually yield 800 billion barrels of oil, according to government estimates.

At the current consumption rate of roughly 20 million barrels a day, 58 percent of it from outside the United States, 800 billion barrels is enough to satisfy America’s oil addiction for more than 100 years—without importing a single drop. In reality, of course, a new and ready supply of oil would virtually guarantee increased consumption. And any petroleum extracted from domestic oil shale would inevitably be combined with imported oil as well as domestic oil from other sources to meet the growing demand, further extending our dependence on oil.

President Bush has been previewing the notion of squeezing oil from stone in his energy speeches for the past couple of months, and today [July 22, 2008] the U.S. Interior Department is scheduled to propose regulations for a new program to sell leases that would allow oil companies to extract oil from shale on federal lands, primarily in the Green River Basin of Colorado, Wyoming and Utah.

EPA Wants to Know What You Think

Monday July 21, 2008
Have you ever wanted to give the EPA a piece of your mind, or just tell the agency what you think about some environmental topic? Well, now you have the chance to do just that by adding your comments to the EPA blog: Greenversations. Every week, the EPA posts a new question and invites all comers to share their thoughts, and to read what others have to say on the subject.

This week's question: What do you use: paper, plastic, or reusable bags?

Paper or plastic? We take shopping bags for granted, especially at the grocery store, and it’s easy to fill up several bags per trip. Both paper and plastic bags use resources, multiplied by the billions of bags used annually worldwide. You can reuse and recycle both paper and plastic types, which delays their being thrown away, or you can reduce waste with permanent bags.
