Four, straws that are carelessly thrown away may inadvertently be eaten by animals. As a result, the animals get sick or even die. Getting rid of straws is a very minor matter, but as one of the most famous humanitarians of the 20th century, Hellen Killer, said, “No one makes a greater mistake than those who do nothing because they can only do a little.” Join the chorus of voices, “No Straw, please.”
