Recently, the news reported that one special kind of rhino from Africa just passed away, which meant the disappearance of this lovely creature. What a great pity. The tragedy is caused by the damaged environment, while human being must be blamed for it, because we h**e done so many bad things to pollute the environment and make the nature lose its balance. In order to make up our faults and s**e our offspring, it is in need of protecting the environment. As the ordinary people, we can do the small things, such as do not throw away the rubbish and join some activities to bring the world green, like planting trees. Every small act can make a difference. Some day, when we live with the environment friendly, what we do is worth.
