Litter Is a Problem in Our Cities
Litter is garbage – like food, paper and cans – on the ground or in the street. Where many people live together, litter is a problem. People don’t always put their garbage in the garbage can. It’s easier to drop a paper than to find a garbage can for it. But litter is ugly. It makes the city look dirty, and it spoils the view.
The wind blows papers far away. Often they are difficult to catch. When they blow against a fence, they stay there. The fence looks like a wall of garbage.
Litter is a health problem, too. Food and garbage bring animals, which sometimes carry disease.
Some people want to control litter. They never throw litter themselves, and sometimes they work together in groups to clean up the city. In most places litter is against the law. The law punishes people who throw garbage on the streets. They usually pay a fine, and occasionally they go to jail.
Two famous sayings in the United States are: “Don’t be a litterbug!” and “Every litter bit hurts!”
