Regarding the July 1 front-page article “An oil rush up north”:

Our addiction to oil is about to take another step further leading to disaster. Yes, oil can be obtained from the tar sands in Canada but at a tremendous cost to the environment. The article pointed out that it requires three barrels of water to produce one barrel of oil, but it did not explore what ultimately happens to the water, which is mixed with toxic chemicals and injected deep into the earth, threatening the water supply.

Currently the world is experiencing a problem with supplying potable water to its inhabitants. Why exacerbate the problem? And the proposed pipeline to bring the tar-sands oil to the United States would run through the heartland of our country. What effect would a major oil spill have on our breadbasket? When will sanity rule and stop the Keystone XL pipeline?
