Kudos to President Obama for his courageous decision to deny a permit for the Keystone XL pipeline. As a former resident of Colorado, I can vouch for the fact that the Ogallala Aquifer that would have been threatened by the pipeline is a crucial source of drinking and agricultural water for much of the Midwest.
Keystone I, built several years ago, has had a long and sad history of accidents and spills. With this decision, millions of future Americans will be spared a legacy of pollution.
