Sure.
The federal government produced a science assessment before proceeding with listing plastic manufactured items as a toxic substance on schedule 1 of CEPA. That assessment looked at all of the various ways in which both microplastics and macroplastics are impacting the environment, wildlife in particular. That's where the science is strongest at the moment. There is evidence of animals strangling themselves on plastic or basically feeding on plastics and starving themselves of real nutrients. Those are some examples of how macroplastics have affected and killed or maimed wildlife.
On microplastics, the research is evolving every day, but already the federal government science assessment has found evidence that microplastics can change the gene expression of small aquatic organisms. That means we're changing life in our food webs and ecosystems. Plastics are effectively changing ways of life in those small organisms. There's no reason to believe that this will not impact other organisms, including larger ones and mammals, although that research is still being done.
These are two examples in the science assessment.
More recently, microplastics were found in humans in the arteries of people who had suffered heart attacks: There are microplastics in their plaque. People who had more microplastics had worse outcomes from heart disease. This is very concerning. Is there a one hundred per cent cause-and-effect out of that study, which was published in the New England Journal of Medicine? No, there is not, but this is where we need a bit more research.
We just need to proceed with caution. We know the damage is happening. We know the prevalence of plastic. This is why we're urging the focus to be on how we reduce plastic at its source and how we make sure that our products and packaging are reused and repaired as much as possible to stop the loading of all of this plastic into our environment and our bodies.
