I think I can safely say that it's our opinion that it's all of us. We are all contributing to this problem, and we all have to increase our awareness and understanding of the issue and to step up.
If we look at Canadian shoreline cleanup data, we can find identifiable items like plastic beverage bottles, cigarette butts, bottle caps or sometimes pieces of polymer fragments, so there is clearly a consumer element to that, coming from activities on or in the water, or upstream in the watershed.
We know that there is a heavy aquaculture and commercial fishing fleet, and there are a lot of efforts right now to evaluate the potential role they play in releasing, surreptitiously or deliberately sometimes, plastics into the receiving environments.
A lot more awareness there.... I think this is a good opportunity for education, in particular with the activities on the water.
In terms of microplastics, one of the interesting discoveries we made is that in the Strait of Georgia we have over 3,000 particles of plastic in every cubic metre of sea-water. These are all microplastics, smaller than five millimetres. Most of those, 75% of those are fibres.
In our extensive surveys up in the Arctic with Fisheries and Oceans Canada and One Ocean Expeditions where we are collecting sea-water, we find that 91% of the microplastics up in the Arctic in sea-water are fibres. The majority of these, in both situations, are polyester.
So we are very interested in furthering our very good work with the textile makers and apparel retailers, and our work with the waste-water treatment plant operators, because we're really finding a significant release of microfibres into local waters from the clothing that we are washing.
