The rapid pace of Calgary’s expansion since the 50s raised questions from academics and concerned citizens, who described it as a perfect example of urban sprawl and deemed it unsustainable from the human, economic and environmental point of view. This podcast is a series in 3 episodes that aims at exploring this question, through interviews with experts to discuss the threats associated to this phenomenon from three different points of view: the threats towards Calgary inhabitants, the threats towards biodiversity and the threats towards the cultural heritage of Indigenous people. This podcast was created as part of the Canadian Wilderness Stewardship Program run by CPAWS.
