Keeping a beach clean is not a job for one individual. You can organize for a clean up session by picking up the trash with the help of some friends. But this is not the best solution for keeping a beach clean and is only a temporary initiative. The beach would again become dirty after some days. Hence the best way to keep a beach clean is to spread he message as to why it is important.
You can do this by telling people about the hazards of not keeping the beach clean to the environment and health of people. You can use placards and attractive slogans to drive home the point. Then installing pans for garbage would also help to keep the beach clean. But ultimately one should realize that only our sense of cleanliness and its importance would help in maintaining cleanliness not only in the beach but also in any other place as well.
