Littering is one of the worst crimes against our environment, but sadly it keeps happening, and doesn’t seem like there would be an end to it anytime soon. However, some people still try to fight against it, and even if they can’t save the entire planet, they will do anything in their power, small step at a time, to bring a change to our society.
This person noticed his neighbor was constantly littering the sidewalk with his cigarette butts, and he decided to do something about it. After he circled the block, picking all the cigarette butts he could find, he didn’t just throw them in the trash, where they belong, but returned them to his neighbor, just to give him something to think about.
