A public dialogue between activists, scholars, scientists, and policy experts tackling the issues at the forefront of plastics pollution policy. The panel will focus on activating resistance to mechanisms of petro-chemical pollution affecting human health and ecosystems. The known and unknown effects of plastic as a matrix for chemical accumulation, the dangers of its circulation in waterways, and the uneven distribution of its impact on communities are among the primary concerns of the movement that calls for “turning off the tap” and regulating the plastics industry and future development.

With Vanessa Gray, Mark Fisher, Michelle Murphy and Chelsea Rochman. Moderated by Heather Davis.

This event is held in conjunction with the exhibition Plastic Heart: Surface All the Way Through on view at the Art Museum at the University of Toronto from September 8 through November 20, 2021.

Vanessa Gray iVanessa Gray (She/Her) a 28 year old Queer Anishinaabe kwe from the Aamjiwnaang First Nation, located in Canada's Chemical Valley. As a grassroots organizer, land defender and educator, Vanessa works to decolonize environmental justice research by linking scholarly findings to traditional teachings. Vanessa is a co-founder of Aamjiwnaang & Sarnia Against Pipelines (ASAP), host of the annual Toxic Tour of Canada's Chemical Valley. She continues to take part in a diversity of tactics such as direct action, classroom lectures, co-hosting Toxic Tours and Water Gatherings.

"Growing up in Aamjiwnaang surrounded by petrochemical refineries has always made me question my relationship to the environment. Being Indigenous in Canada continues to be the struggle to uphold my responsibility to the Anishinaabek Territory. Education and understanding our interconnected struggles is essential to our ever-growing movement, but we can't afford not to take risks for a sustainable and just future."
