“Where does the body end and ‘non-human nature’ begin? When we recognize that human bodies are directly affected by their environments, we are forced to acknowledge that humans are not simply agents of environmental change, but objects of that change” – Linda Nash, Inescpable Ecologies
Last week I was surprised to hear about the toxic leak of nitrous oxide at Vale’s Copper Cliff Mine in my hometown of Sudbury, Ontario. Residents near the mine were told to leave or stay inside with their windows and doors shut until the toxic leak had cleared. Air quality readings showed levels of nitrous oxide that were about fifteen to twenty times higher than usual. A high-ranking mine employee told the CBC that the leak posed “no risk to the community,” although exposure to nitrous oxide is known to cause respiratory issues and it can be lethal in high doses. I wonder if after the gas had dissipated, and the residents and workers returned to their regular activities in the area, if they were completely safe from exposure? And what about the150 kilotonnes of sulphur dioxide that Vale’s Copper Cliff mine continues to release every year, despite its promise to reduce emissions? Is Sudbury a safe place to live today, even if it is a little greener?

Growing up in Sudbury, I didn’t think much of the industrial landscape that surrounded me. A
mining town with its black rocks, stunted trees, slag hills, and iconic Superstack, Sudbury was home. It was not until I began to venture outside of the Sudbury region that I realized something was very unnerving about my hometown. Trees growing in other cities, like Ottawa or Toronto were much taller and healthier. There were also several different species of trees besides birch or spruce lining the forests along the highways just outside of Sudbury. Rocks outside of town were any colour but black, and as far as I could tell, there were no slag hills, orange streams, or green-ish tailings ponds at our family’s cottage, about a 40 minute drive away. These other environments that I visited were not pristine because most ecosystems have been manipulated by humans. But why was Sudbury so different?
