Yes. Again, it's a combination of solutions that we need to adopt.
As I mentioned before, extended producer responsibility is going to be a significant change. In terms of other measures, the number one item that we pick up on our streets, on our beaches and in our waterways is cigarette butts. I'm not sure how we're going to change that behaviour of flicking your butts out onto the street. We are working with companies and municipalities to install stormwater filtration systems, called litter traps and gutter bins, that can be easily removed and that catch this material when storm events happen that wash this material down into a drain.
These are systems that allow us to educate people about what's happening. I'm not sure that every municipality can put a filter into a drain in their municipality. It just wouldn't be practical.
