My name is Yu Ruofei, I am a pupil of grade five. I like travelling and I like marine organism. Diving is my favourite sport. Through diving, I learned that human littering causes serious pollution to the ocean. Global warming leads to massive coral whitening. I want to protect the beautiful ocean. So on my eleventh birthday, I joined MissVsea mermaid school and became a real little mermaid. I am determined to be a volunteer to protect the ocean!
