For decades, the Alberta oil sands seemed like an unstoppable juggernaut of growth and money. Then the 2008 recession hit, and the tides turned. An increasing focus on the environmental effects of the area took shape, and an intractable debate over its existence crystallized. Through the eyes of oil sands shift workers, scientists, activists, and Indigenous peoples, Chris Turner chronicles the story of the oil sands in his book, "The Patch: The People, Pipelines, and Politics of the Oil Sands." He joins The Agenda to discuss his plea for nuance in a fiery debate, and to discuss the question: what next for Alberta's oil sands?
