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 （惡化） 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（生態(tài)系統(tǒng)） on earth.
Much of the worsening situation could be changed if all sides make more effective efforts. Fortunately the solutions are in sight. Advanced science and technology will be introduced and applied. More laws on environmental protection will be drawn. We are sure to live in a better and cleaner world， and the earth will certainly remain our permanent （永久的） paradise （天堂）。
