Do you really know what happens when you throw gum wrappers, soda cans, lollypop sticks or any type of litter out the window?  You are harming our beloved Earth, that’s what.  Did you know we need oxygen to breathe?  People are cutting down trees (and trees produce oxygen) and are they aware that they are harming our oxygen supply?  We need to stop harming our environment or else humans will become extinct.
