Yes, that's a big target as well. Food containers are a more accessible problem for most people, but we are working with organizations that lobby for improved fishing regulations.
One of the things we do is monthly beach cleanups. While we're cleaning a beach, we'll section off an area and carefully count and categorize the trash we find in that area (such as fishing nets). We share the info with organizations like our local university and department of fisheries and oceans, so that they'll have recent evidence that they can use when asking for regulatory changes.
Also, the UN says we are a decade or so from fishing all saltwater fish to extinction.
What do you think about banning the production of plastic fishing nets?
