The other day, our class had made an interesting outing. Though we enjoyed the charming scenery and fresh air all the way, we were astonishing to see some bad behavior. Some people threw rubbish here and there, turn the public place into a large dustbin. Others carved word on famous buildings or picked flowers casually.
An eco-friendly journey not only allows us express our love for nature but need our responsibility. As we enjoy the beauty of nature, we can't damage them. Only when we improve our aware of eco-friendly travel can the earth become more beautiful. After all, which matters most for us is the earth because it is the only place for us to live.
