How does tar oil sand effect our souroundings

In Canada, the oil industry is transforming one of the world's last remaining intact ecosystems into America's gas tank.

Alberta's boreal forest and wetlands are home to a diverse range of animals, including lynx, caribou and grizzly bears, and serve as critical breeding grounds for many North American songbirds and waterfowl. Oil companies are scraping up hundreds of thousands of acres of this wildlife haven to mine tar sands -- silty deposits that contain small amounts of crude bitumen.

Extracting tar sands, and turning bitumen into crude oil, uses vast amounts of energy and water, and causes significant air and water pollution, and three times the global warming pollution of conventional crude production. The rush to strip-mine and drill tar sands in the boreal will destroy and fragment millions of acres of this wild forest for low-grade petroleum fuel.
