You know the feeling when you're driving along a road, come to a red light and see someone throw a cigarette butt out the window. It makes you mad. They don't think it's littering.
Have you noticed the cigarettes on the sidewalk, against the curb and in the sand where all the children are playing as you walk through the park? Or when you're hiking and you see a cigarette in the grass, in nature! The grass could easily light on fire.
