Try as we might to stay away from polarizing issues on our show, it seems you can’t talk about health and healthcare without touching on these controversial topics. The Keystone XL Pipeline is one of those issues. It could have a significant impact on the health of communities in the tar sands production areas along its route and refinery fence-line communities where the heavy sour crude will be processed. In addition, the emissions from tar sands will exacerbate climate change, affecting public health more broadly even than the widespread direct impacts of the tar sands industry. Director of Public Policy for California Nurses Association Michael Lighty talks with Casey and Shayne about the health and environmental concerns related to the Keystone XL Pipeline.
