Earth is our common "home", and is a very beautiful home, then there is blue sky with white clouds, a tree with red flowers, birds contention, how beautiful all the ah, but that we have not thought about how to protect the earth ? October 15, 2003 astronaut Yang Liwei and the family telephone said excitedly, "I - see our beautiful home", which sounds from space, how many Chinese people moved, the number of foreigners Yeah.

　　Today, however, when we again face the "beauty of our home", we can also say? Blue sky, how life used to be a brilliant landscape, now trapped in the gray, the clean air become very close to a desire to dream. Faced with an increasingly serious air pollution, looking at the sky, you say? Know of a small village called Demonstration of field do? The place was surrounded by the Castle Peak, Green River Flows, a beautiful place ah! However, the villagers are aware of the environment, no one important, they are deforestation, land reclamation, deforestation, forest gradually disappeared, the stream gradually dry, well water gradually withered. Today, this no longer see the mountains and never see green water, and the village people use very little water, wash your face, then keep feet, and finally carefully pour the water in a vat .... .. keep pouring in ah ....... This is a natural right to their punishment, which is the earth for their ambitions ah!

　　Students is only one earth. Earth is our lovely "home"! Let us join hands, for our home planet to create a better tomorrow.
