Topic:
Some people say that exploration of outer space has many advantages; other people feel that it is a waste of money and other resources. Which view do you agree with? Use specific reasons and examples to support your answer.

Sample:
With the development of outer space exploration, many people begin to doubt whether the endeavor is worthwhile. It is true that some money and other resources must be spent in this area, but in my opinion, human beings should continue the adventure because it can add to our knowledge, acquire new resources, and even find places where human beings can live.

To begin with, the exploration of outer space will add to our knowledge about the universe as well as about the earth. Although human beings have been living on the earth for thousands of years, we know very little about it. For example, we are not even sure about how the earth came into being, why the dinosaurs disappeared altogether from the face of the earth, and whether there is life on other planets. The attempt to explore outer space will certainly help us answer all these questions and bring us a great many benefits.
In addition, the exploration of outer space may help mitigate the energy crisis. As we all know, our oil, coal, and other conventional fuels will be exhausted in the near future. Although the scientists are looking for alternatives on the earth, such as nuclear power, we may launch spacecraft to the moon or other planets, where natural resources might be abundant and untapped.

Last but not least, the exploration of outer space may find new habitation for human beings. Our earth is becoming more and more uninhabitable because of the population explosion. Although we have tried various means to relieve the burden of overpopulation, such as the building of skyscrapers and the practice of birth control, but the problem is getting increasingly serious. The best way, I think, is to turn our eyes to outer space,. Some scientists are already working on the possible human migration to another planet, say, the Mars.
Since space exploration has so many important advantages, there is no reason for any objection to it. Those who only see the financial and material resources used for this undertaking are near-sighted. Would they leave the earth in a state of overcrowding, energy shortage, and severe pollution? Would they remain ignorant of the earth upon which human beings depend for survival? If not, they should change their position and support the scheme for space exploration.
