    In the past, man did not have to think about the protection of his environment. There were not many people on earth, and natural resources seemed to be unlimited.
    Today, things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue like this, human life on earth will not survive.
    Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on the land. Yet, we continue to use bigger and more powerful machines to cut down more and more trees.
    We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste products are still put into rivers or into the sea, and there are few laws to stop this.
    We know, too, that if the population of the world continues to rise at the present rate, in a few years, there will not be enough food.
What can we do to solve these problems?
    If we eat more vegetables and less meat, we will easily get more food. Land that is used to grow crops can feed five times more people than land where animals are kept.
    The world population will not rise so quickly if people use modern methods of birth control.
Finally, if we educate people to think about the problems, we shall have a better and cleaner living place in the future.

举一反三

It's March, 2050.

   Frank and Mary Smith wake up in their comfortable house in the morning and switch on the bedroom computer to get the latest news. They used to read the Times, but changed to electronic newspapers many years ago.
   There is the usual news about space: another space flight has returned from Mars and scientists have discovered a new planet. Then they turn to business news: the US dollar has risen greatly in Shanghai, one of the world's leading business centres. Mary tells the computer to buy 5,000 dollars, and there is a quick response that it has been done.
   As they watch the screen, Mary orders one of the household robots to make coffee for them.

   Frank disappears into the study to join a video conference with his partners around the world. He is a computer engineer, working for several companies. This is his third job: he used to be in marketing and then television.
   Mary has a quick look at the shopping channels - the usual selection of electric cars, household robots and cheap travel offers - before picking up the video phone to talk to her assistant. She also has a job and she is doing medical research. Both she and Frank used to have an office desk in London, but in 2014 they decided to move to the seaside and work from home.
   Frank and Mary have one daughter, Louise, who also has her own workstation at home. She goes to school only one day a week, mainly to play with other students. Classrooms disappeared in 2030 because there was no longer any need for them: communications systems have made it much easier to learn at home.
   Louise, now thirteen, is studying Chinese at present, which has become a world language as important as English. Louise has many Chinese friends. They communicate by computer.
   According to the family doctor, Louise will live to at least 130. Her wish is to work for a few decades (十年) and then spend her time on music and painting.
