Many years ago, I lived in my hometown, which was a small countryside, but I loved everything there. I remembered that the sky was very blue and the river was so clean that I could see fish swimming. I was so close to nature and I enjoyed what the nature brought to us. But now, when I go back to my hometown find that the environment has been polluted badly. I can barely see birds flying in the sky. I miss the beautiful nature. It is such shameful for people to destroy the environment. It is everybody's duty to protect the environment. We can't live if we don't get along well with nature.
