The proposed Keystone XL tar sands pipeline would pump 900,000 barrels of extra-dirty oil daily through the fertile breadbasket of the United States to the Gulf Coast from where it can be exported overseas. The pipeline would hobble the steps the country is making in its ongoing battle against climate change. Americans are already experiencing the consequences of climate change, at home and in their pocketbooks, with more frequent and stronger storms, raging wildfires, and drought. The costs associated with extreme weather events due to climate change will only increase in the coming years. Tar sands will only make these consequences worse, while expanding dirty oil mining practices, discouraging investment in a clean-energy economy, and razing virgin Boreal forestland that has the natural capacity to store carbon.
