Passage Three
The whole industrial process, which makes many of the goods and machines we need and use in our daily lives, will unavoidably create a number of waste products which upset the environmental balance. Many of these waste products can be prevented or disposed of (外置) properly, but clearly while more and more new goods are produced and made complex, there will be new, dangerous wastes to be disposed of, for example, the Waste products from nuclear power stations. Many people see pollution as only part of a larger and more complex problem, that is, the whole process of industrial production and consumption of goods. Others see the problem mainly in connection with agriculture, where new methods are helping farmers grow more and more on their land to feed our ever-increasing population.
Whatever reasons behind it, there is no doubt that much of the pollution caused could be controlled if only companies, governments and people would make more efforts. In the home there is an obvious need to control litter (乱扔的废物) and waste. Food comes wrapped up three or four times in packages that all have to be disposed of; drinks are increasingly sold in bottles or tins which cannot be reused. This not only causes a litter problem, but also is a great waste of resources, in terms of glass, metals and paper. Advertising has helped this process by persuading many of us not only to buy things we neither want nor need, but also to throw away much of what we do buy. Pollution and waste combine to be a problem everyone can help to solve by cutting out unnecessary buying and careless disposal of the products we use in our daily lives.

B. Less land will be used for agriculture.
C. New environmental problems will have to be dealt with.
