You can collect and recycle plastic bottles and cans. You don't need to take a trash bag and discover around beaches for looking bottles and cans. Just, place a large box, lined with a garbage bag and put a signboard on your box like “Please Recycle!" people come naturally and put their waste cans into them.
Method 4
You can entertain beach visitors if you are good in playing a musical instrument, you can either sing or develop a mime routine or juggle. Magic acts and stand-up comedy can also drive lots of peoples on beaches if you are a good magician or if you can do some stand-up comedy.
