We live in a world of plastic. From the clothes we wear, the electronics we use to the food we buy, our lives our surrounded by, and depend on, plastic products. Over time, all of these plastic products break down into smaller and smaller pieces to become ‘microplastics,’ or plastics smaller than five millimeters. As we study microplastics, we are learning that they are everywhere – in the air we breathe, the water we drink and the food we eat. In this talk, Dudas will lead us through a day of plastic use, how and where we use and generate microplastics, and what we can do about it. Sarah Dudas is a biologist at Fisheries and Oceans Canada, a biology professor at Vancouver Island University and an adjunct assistant professor at the University of Victoria. For the last seven years she has led the Ecological Interactions Research Program, working with federal and provincial governments, industry and non-profit organizations to study the effects of human activities on coastal ecosystems. Her research includes investigating marine biodiversity across regional and local scales and the effects of historical and contemporary shellfish farming practices on surrounding ecological communities. Recently, she has focused on the issue of microplastics and their presence in the marine environment and our seafood. Dudas’s professional affiliations include the Hakai Institute, Canadian Society of Ecology and Evolution and the Aquaculture Association of Canada. She is also a member of the United Nations-led Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection microplastics working group. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
