Estuaries and coastlines capture most plastic before it gets out to sea, providing a chance to stop ocean pollution

If you ask someone where plastic ends up, they will usually say the ocean. It's not a surprising answer because we have known since the 1970s that plastic is accumulating in the subtropical oceans, far from land.
