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.

Suzuki Diaries: Future City

"Eighty percent of us now live in an urban setting, and I think that the solution to our environmental problems is not to say 'we've got break down cities and get everybody back to the land' – that would be disastrous – but we have to make cities our major habitat…we have to make them more in balance, I think, with the rest of the things that keep us alive." David Suzuki Cities are where most Canadians live. And, as we head into the future, how we adapt to the needs of expanding cities will have a huge impact on their livability. Food, land use, housing, energy, waste – how we tackle these issues will determine whether our cities evolve, or whether they decline. In a new instalment of Suzuki Diaries, David and his daughter, Sarika, set out to discover whether some of Canada's biggest cities are ready for the challenges of the future.
