Keep America Beautiful
After World War II, many companies decided to sell things in packages that could not be used again.  They did this because it was cheaper than using bottles and cans again.  Many of these companies did not want the government to make laws telling them what to do.  For example, in 1953, the state of Vermont passed a law against one-use bottles. It was because farmers said people were throwing the empty bottles into haystacks and that cows were eating them.  This type of law is called a "bottle bill."
