Nature's Past: Canadian environmental history podcast

Nature's Past: Canadian environmental history podcast is a monthly episodic audio podcast about the environmental history research community in Canada, sponsored by the Network in Canadian History and Environment. The podcast was first produced out of the University of British Columbia in Vancouver, BC. It is now produced in Toronto, Ontario in the Department of History at York University. New episodes are released each month, usually in the third week of the month. Listeners can subscribe to the podcast through RSS or iTunes.

It is the first audio podcast to focus on Canadian environmental history. The podcast launched on 10 December 2008 with an episode about the history of Toronto's Don River. Since then, episodes have explored issues in environmental history, including dam construction in British Columbia, wildlife management in the Northwest Territories, environmental justice in Hamilton, Ontario, e-waste, and natural resource conflicts. The podcast has a wide audience of listeners from Canada, the United States, the UK, Australia, New Zealand, Japan, and many other places. It has been reviewed positively on a number of history blogs.
