TransCanada -- the company behind the notorious Keystone XL pipeline -- now wants to build an even bigger and more dangerous tar sands pipeline, called Energy East.

Energy East would be the largest oil pipeline ever built in North America, carrying 1.1 million barrels of tar sands oil a day 3,000 kilometers (1864 mi.) from the remote tar sands oil fields of Alberta all the way to the Atlantic Ocean.

Climate scientists have warned for years that burning Alberta's tar sands oil would be "game over" for our climate. And a new scientific report finds that it would put the drinking water of 5 million people at risk.

We stopped Keystone XL, and now we're fighting to stop Energy East.

Will you chip in today.

Tar sands oil is one of the dirtiest, most polluting sources of energy ever used. It's a thick, peanut butter like substance that must be blended with a highly toxic cocktail of chemicals and transported through super high pressure pipelines.

Tar sands oil sinks in water, making it virtually impossible to clean up, and tar sands pipelines have been especially prone to leaks. In fact, earlier this month, TransCanada had to shut down the Keystone XL pipeline because of a leak that was discovered not by TransCanada safety inspectors, but by a local rancher whose land was affected by the leak.

And worst of all, tar sands oil is three to four times more damaging to the climate than conventional oil. That's why top climate scientist James Hansen has said that burning Alberta's tar sands oil would be terrible for the climate.

The latest report finding that the drinking water for a stunning 5 million Canadians would be at risk could be a game changer, but only if we take advantage now.
