The earth's biosphere (the surface layer of the planet and the surrounding atmosphere) provides the land, air, water, and energy necessary to sustain life. This life-support system is a complex, interdependent one in which energy from the sun is changed into food for humans. The entire system depends on the sun, reasonably moderate temperature, and enough supplies of oxygen, pure water, and fertile soil.

Since the earth's creation millions of years ago, the ecosystem has worked as an interdependent system relatively undisturbed by outside forces. But recently, especially since the Industrial Revolution, human beings have begun to disturb the balance of nature. Natural resources have been severely depleted (消耗) (forests have been destroyed, fertile land worn away, water polluted, and minerals used up), and the life-support system of air, water, and land has been poisoned by a variety of waste products and chemicals.

The degree of these problems was noted in a report by the U.N. Developing Council on Environmental Quality. This report predicted that if present trends continue, the world will be more crowded and polluted and less stable ecologically and politically than the world we live in now.

The twin problems of resource shortages and pollution are caused by three social forces.  First, the tremendous increase in population growth constantly increases the demand for food, energy, and other products. As the current population continues to increase, the stress on an already overburdened environment will be increased．A second source of the problem is the concentration of people in urban areas, where the ecosystem simply cannot absorb their waste products. Finally, environmental problems are worsened as more and more nations move toward modem development: an increased reliance on modern technology. As these nations become more technological, they will consume more energy, deplete more natural resources, and create more waste products than the biosphere can absorb.

       D．the destruction of life-support system and its causes

I used to be a very self-centered person, but in the past two years I have really changed. I have started to think about other people        I think about myself. I am happy that I am becoming a        person.

I think my        started when I was at Palomar College. At first, I just wanted to get my       and be left alone. I thought I was smarter than everyone else, so I hardly ever         to anyone in my classes. By the end of my first semester, I was really        . It seemed as if everyone but me had made friends and was having fun. So tried a (n)        . I started asking people around me how they were doing, and if they were having trouble I        to help. That was really a big        for me. By the end of the year, I had several new friends, and two of        are still my best friends today. 

A bigger cause of my new        , however, came when I took a part-time job at a Vista Nursing Home. One old lady there who had Alzheimer’s disease became my         . Every time I came into her room, she was so        because she thought I was her daughter. Her real daughter never        her, so I took her place. She let me        that making others feel good make me feel good, too, when she died, I was        , but I was very grateful to her.

I think I am a much        person today than I used to be, and I hope I will not        these experiences. They have         me to care about other people more than about myself. I        who I am today, and I could not say that a few years ago.
