　　The earth is being filled with waste material such as plastic bags and   other rubbish. Is this really happening? What are some solutions to this   problem?

　　Model Answer:

　　Over the past few decades, the increasing amount of industrial wastes and   household garbage has become a major problem in many countries. People have   questioned what caused this problem and what can be done to improve the   situation. In my opinion, two of the most critical causes of this waste material   problem are the increased consumption and a shortage of space for landfill.

　　To begin with, modern lifestyle has contributed greatly to the increasing   amount of waste and garbage we produce everyday. In other words, we have turned   into a materialistic and mass-consumption society where we use more and throw   away more than ever before. Moreover, countries are running out of space to   store garbage and waste material. In fact, securing land for waste disposal   raises controversies in many countries.

　　To solve this intractable problem, every citizen needs to participate in   producing less garbage. For example, we can bring our own personal shopping bags   instead of using plastic bags provided by stores and shops. Besides, the   government can enforce stricter laws on companies to use biodegradable packaging   or use recycled material. Indeed, this alone can eliminate much of the waste   which is sent to at land fills. Companies can also contribute by developing new   raw material which is recyclable and will ultimately lead to less garbage. One   good example of this is that tire companies develop new tires for cars which are   not made of rubber but of new biodegradable material.

　　As discussed above, individuals, business and the government can share the   responsibility to reduce the amount of waste material and to save the earth. I   hope that in the future our offspring will be better off with the well-preserved   environment.
