A tailings pond at the Mount Polley gold and copper mine in central B.C. failed last month and released millions of cubic meters of waste water, triggering a state of emergency for the local community. An aerial footage taken from the affected area reveals the extent of the spill, while residents and experts express their fears about the long-term impact on the environment and local fish stocks. Grand Chief Stewart Phillip of the Union of B.C. Indian Chiefs stated that "Like the Exxon Valdez, Mount Polley will be synonymous with one of the most disastrous environmental events in British Columbia".
