Hello to the east coast of Canada, one of our three very important coastlines. The billions and billions of dollars in terms of natural resources and commercial, sport, recreational and indigenous fisheries are something we want to protect.
The first point I would make in response to your line of questioning is that, once plastics are released into the ocean or into the environment, the genie has been let out of the bottle. We all do the right things, as you do—and thank you for doing so—in cleaning up where we can. That is an important activity; it does clean up a small amount. It generates data, and it gives us a direct channel of communication to Canadians. For example, last year we had more than 60,000 Canadian volunteers cleaning up more than 3,000 kilometres of shoreline.
That's important in terms of education and data collection. It does—you said it yourself—cosmetic justice to the big issue out there, and that speaks to the need to turn off the tap at the source to prevent these things from getting into the ocean. These huge ocean cleanups are worth exploring, but they're never going to address the problem. We really have to turn off the tap at the front end, and that's understanding where these things are coming from.
Of course, there are many different sources of plastics in the ocean. You mentioned the fishing sector's plastic: polypropylene nets, polyethylene pipes, tubes, lines, ropes, fishing gear of all shapes and sizes, often made largely of plastic. There are best practices on board vessels in terms of fishing as well as design, like the use of hemp, for example, as an alternative to polypropylene, and cleaning up of derelict fishing gear.
This is one example of macroplastic, large plastic items, that is really worth looking at. Derelict fishing gear is killing hundreds of thousands of seabirds, turtles, fish and marine mammals every single year—that's the ghost gear. There are really good programs in other parts of the world, and we're just starting to look down that pathway in Canada. I think that's very important to address.
Another point I would make is that, when we see a plastic bottle, a plastic bag, a net or a bottle cap on the beach, we can either clean that up or leave it there. My example is used to illustrate the life cycle of that item. If we choose not to clean up that plastic bag, it's going to be here five, 10, 50 or 100 years from now. It may not be intact, but chemically it's still going to be out there, because plastic is basically geological material. It's not going to degrade chemically; it's going to degrade physically into smaller and smaller bits of microplastics, translating that risk from charismatic creatures down into the zooplankton.
I think you touched on a number of points that are really worth taking home, and it really speaks to the need for better design and better practices in the field, certainly continued cleanup and investment in innovation and discovery that help us create a forward-looking, practical solution or a set of solutions that will help protect the Canadian economy.
