Shattered Ground

As Shattered Ground reveals, some see fracking as a great opportunity for money and jobs, and one that provides cheap, clean fuel. But, for others, the possible human health costs of this new drilling technology have motivated a large and vociferous anti-fracking movement. The debate over fracking has been echoed in the Oscar-nominated documentary Gasland and in Promised Land, the new Gus van Sant's feature film starring Matt Damon. Fracking's critics consider the industry a potential environmental disaster, citing chemical contamination of air and water. With pipelines proposed, terminals for liquefied natural gas (LNG) requiring billions of dollars of investment, and huge shale beds lying underneath highly-populated areas of the Canada and the US (including southern Ontario and the GTA), fracking is an issue that could affect every one of us.
