Michael Harcourt, Chair of Quality Urban Energy Systems of Tomorrow (QUEST), and Seth Klein, BC Director at the Canadian Centre for Policy Alternatives, were the final two presenters on a panel of four put together for our March workshop on rethinking growth and prosperity, De-growth: A Critical Juncture?. Harcourt discusses how, in the face of rapid population growth, developing urban spaces in a manner that creates a liveable and sustainable environment for city residents is vital and, in fact, presents a massive economic opportunity.
