You have both direct and indirect harms.
As direct harms, you have the suffocation of marine life and the ingestion of plastics, which can contaminate seafood and be passed through the food chain back to us. Plastic pollution does not stop at the shoreline. It can come onto our dinner plate. It can also degrade water quality. It can degrade critical ecosystems like kelp forests and coral reefs.
Then you have the chemicals in plastics. As mentioned before, there's a huge emerging sector trying to figure out their ecotoxicity to wildlife and water quality, as well as to people. Every week, we're getting a new study coming out. I implore Environment and Climate Change Canada to work with Health Canada to have a comprehensive understanding of what they're doing to our ecosystems, our food, our wildlife and ourselves.
