WASHINGTON — Oil and gas companies injected hundreds of millions of gallons of hazardous or carcinogenic chemicals into wells in more than 13 states from 2005 to 2009, according to an investigation by Congressional Democrats.

The process, which is being used to tap into large reserves of natural gas around the country, opens fissures in the rock to stimulate the release of oil and gas.
Hydrofracking has attracted increased scrutiny from lawmakers and environmentalists in part because of fears that the chemicals used during the process can contaminate underground sources of drinking water.

Cultivated in the 70s, earthships are made of tires, cans, bottles and adobe and are a real option for people in developing nations looking to build a very cheap home that can catch rain water. Check out Dan Richfield’s site as he blogs through the build into October 2011- and if you want to head to Taos, New Mexico, he’s looking for volunteers!
