When I was younger we didn't have plastic straws, they were paper. They fell apart halfway through your milk carton, so we went to plastic.
So one picture of a turtle with a plastic straw stuck in its nose and the world flips and laws are made. RSA-Kneejerk-101.
If you gonna get rid of straws, then solo cups and all plastic products should be on the list. Else it is just a show.
