The Earth Is Our Only Home
Some people imagine to leave this fearful world, only to come down to earth. Scientists tell us that of all the stars known in the vast universe, the earth is the only planet on which human beings can survive. But now we are facing the risky problems concerning our existence on earth.
Worldwide environmental deterioration (恶化) is alarming. The earth is plagued with population explosion, energy crisis, lack of food, housing problem and environmental pollution. During the process of industrialization, human beings are pursuing crazily the benefits from the economic growth. Now we have suffered from the results. The overuse of natural resources has affected ecosystem(生态系统) on earth.
Indeed, much attention should be paid to these serious problems. The fate(命运) of the earth is held in our own hands. Countries must make complete schemes and perform them steadily. As individuals, all of us should realize how dangerous these problems are and do our best to keep our only home tidy and clean.
