The oil industry is currently planning a massive project to export millions of barrels more per day of dirty tar sands oil from Alberta, Canada to the United States. Tar sands strip-mining and drilling in Canada’s Boreal forest is the largest and most destructive project on Earth. The decline in oil demand and the rise of alternative energy puts North America on the verge of a phenomenally important step forward toward a new, clean energy economy. Expanding reliance on tar sands is unnecessary, undermines our progress as a nation, and is severely destructive. We have a choice: we can move forward towards a clean energy future with greater national security or remain stuck with the dirty fossil fuels of the past.
