Today I will be talking about my impression is that the high school. The impression was that I had to camp on the environment in the sea with friends. I had the opportunity to make an artificial reef, I feel very exciting because I've never done that before. The camp on the beach, this time it made me learn the more natural. I have made friendships increased. I know that Thailand has beautiful sea and the seabed are prolific. I think this camp is to teach us to know about how to help protect and care for the nature of the sea. Let us take care not to damage the sea and the sea is beautiful forever. And this is the impression I will never forget.
