> I wonder about the river barriers. I buy that the ocean buoys aren’t effective, but it seems like plastic would be a lot more concentrated in the rivers that feed it into the ocean, and the rivers themselves are a lot shallower. I would be interested in reading an expert opinion on whether those make sense. What is it that you're wondering about exactly? The article mentions and explains the progress of the "plastics in rivers blocking" that they're doing, in the "PREVENTING PLASTIC AT ITS SOURCE" section. > Our mission goes beyond cleaning the oceans; we also work to stop plastic from entering waterways in the first place.
