Looking from the outer-space, we will see a greenish blue planet-our mother earth, where we have evolved, cultivated and lived for thousands of years. Take a look at it. The green part represents the land and the blue part the ocean, both of which may appear to be clean from this long distance, but if we go closer and finally expose ourselves to it, a totally different story will present itself.

Neither the land nor the ocean is fortunate enough to escape the door of being polluted. Deforestation, desertification, salination and even population are looming before us as imminent environmental problems. Piles and piles of logs are delivered to big cities leaving only bleak stakes to take their place. Over-grazing has caused an oasis to end up another desert. All the above remind me of a popular song called "where Are the Flowers Gone". And now I want to ask myself a series of similar questions, such as   "Where are the flowers gone?","Where are the rivers gone?","Where are the whales gone ?" etc. 

 

It is high time when we were to answer these question, and found a solution to them. Take desertification for example, it's due to our irresponsible acts of cutting down forests without restoring them; over-grazing and unreasonable agricultural  activities. To deal with it, we need to enhance our managerial as well as technological expertise. If we don't want a room for standing only in the future but enough room for a comfortable life, we need to stick to the family planning policy. And I really don’t consider stopping littering and of dong that.

We can only live on earth once but never twice, and we only have one mother earth but never a pair, further more, we have no choice but never a pair, furthermore, we have no choice but choose earth as our habitat, so we do have a good reason for making every effort to protect it I believe, if we persevere in carrying out and implementing the strategy of sustainable development, we will bestow, not just ourselves but also our children and our children's children, a beautiful blue planet, one that looks beautiful regardless of whether you are on it or in the outer space, and a promising future.
