What do you think of people that litter?

I don't really appreciate them because they're hurting the environment and they may cause another hole in the ozone layer. And I think they're affected because they think: "It's just me, nobody really cares, because I'm only one person.", then they're wrong, because if 1 billion people thought that way, it's not just one person, it's 1 billion people. And bad things are contagious so maybe the next day everyone could convince someone else littering isn't wrong. POOF! 2 billion. A little goes a long way to keeping our earth clean and green!
