Still remember when I was a child, I used to be taught that we have only one earth, at that timing, I learned only by the slogan or naturally thought it was very far far from my age, problem behind the truth will not come to my generation so quickly. As my age grow up, it is soon Again proposed, but this moment is not just the slogan or long long time Here after, it is right soon facing you and me.

In 2008 , 2009 , 2010 , we have continuously faced so many disasters, no matter it is caused by nature or human, greatly, it is telling us we have abused the resource in the earth .

Typhoon take our homeland away with the model of mountain falling stone and sand flow or decay the river bed to cause the building decline such as Hotel falled in East Taiwan. Earthquake shake the lives off with the tsumani flow toward people or housing destroyed. Volcano ash make the air transportation inconvenient all over the Europe, to American continent or Asia. Sand Dust from Mongolia attack the Asia and pollut the air.

These are all caused by the highly built civilization which people try to conquer everything in the world. Air conditioner make you cool in the house from the outside, the exhausted gas will destroy the earth ozone layer, therefore the sunlight go directly into the earth without the shield of protection layer , the temperature is up to make the climate change so hugely. The abuse of the land make the earth change its own period of underground material activity.

All of those, we have only one earth is not just a slogan but also need you and me to implement. We must start from selves. To re-use re-cycle our surrounding resourse. We treat movie 2012 as not a movie. It is a lesson and reminding material to the earth people .our ancestor provide a good environment for us to heritate. We should also protect the earth and make it better for our generations.
