There was a recent study that looked at smaller pieces of plastic and its effect on fish in the Great Lakes. Some of the plastic had come from...

"micro beads, or micro exfoliates, as abrasives in facial and body scrubs. They are too tiny forwater treatment plants to filter, so they wash down the drain and into the Great Lakes. The biggest worry: fish such as yellow perch or turtles and seagulls think of them as dinner."

Plastics are ubiquitous in our society. What are the solutions to this problem???
