Citing concerns about the alleged impact of the proposed Keystone pipeline on an aquifer in Nebraska, environmentalists and President Obama have so far blocked approval for construction.  But according to an article on Bloomberg News, that opposition will likely end up simply benefiting China, and further harming the U.S. economy.  That’s because Canada is considering an alternative to Keystone that would build a pipeline from Alberta’s rich oil sands to the Pacific, where Chinese oil tankers could pick up the oil and bring it across the sea.  So instead of America getting affordable oil from our friendly neighbors to the north, it would mean more energy for China, and less flowing here.
