Dear Sir/ Madam, I’m writing because I am at the beach with some friend last weekend and the amount of rubbish where we found there was unbelievable. I think there are possibly two reason for this. Firstly, people aren’t responsible enough and they threw their rubbish away anywhere. Perhaps we need a few sign and people who patrol the beach. Also, there aren’t bins enough on or near the beach, so I think we need more. Secondly, nobody clean the beach. I think this is terribly in a tourist town. We need people to clean the beach and empty the bins every day. We must definitely to do something about this situation. We must do it right away if we want a cleaner, attractiver beach. Alan |
