The problem is that micro-plastics are eaten by the fish and end up in our plate. It gets worse because pollutants in fish bioaccumulate a lot (fish eats smaller fish, gets eaten by larger fish etc.). Fish high in the food chain like salmon have a lot higher concentration of these pollutants, to the point that it's not even recommended food for pregnant women anymore. Farmed fish also creates bioaccumulation, because it gets fed other smaller fish, like sardines.
