"Each year countless animals die from ingesting plastics of all types including Styrofoam. It takes Styrofoam 50+ years to breakdown and the particles that end up in our environment are filled with toxic chemicals.
Most community recycling centers will not accept Styrofoam in their recycling program, especially if the Styrofoam contained any kind of food or beverage item. That means that virtually every Styrofoam cup that Chick-Fil-A offers, ends up in our landfills, neighborhoods, rivers, streams and oceans.
Because Styrofoam breaks apart into smaller pieces easily, many of these pieces end up being ingested by birds, mammals and marine life with devastating consequences."
