In Alberta the biggest construction project on the planet is wiping out a pristine wilderness and a Native people to feed the world's hunger for energy. What no one expected was for them to fight back. From the scientist whose research could ban the tar sands to Avatar director James Cameron's dramatic intervention, this shocking documentary is a journey through the David and Goliath struggle playing out within one of the major environmental issues of our age. Tipping Point helps us to better understand the trade-offs we make for energy as we approach the end of the age of oil.
