"Throw it away?There is no way," scientists warn us so. What that means, of course, is that as we produce more and more waste, safe places to deposit it are becoming fewer and fewer.
An important change in responding to the problems of waste and its disposal in modern society is the development of techniques for recycling materials that have been thrown away.
Moreover, oil for plastics, trees for paper, and coal and oil to make heat for glass and metal production are also becoming harder to find and more expensive. One solution that can help solve problems of both supply and disposal is recycling, or using the same material more than once.
Some governments are requiring more recycling. Japan already recycles about 50 percent of its household trash.The German government now has a very strict law requiring that most plastics and metal be recycled. Under the new law, automobile manufactures must buy a car back when it is no longer useful.The car must then be separated into materials that can be recycled—metals, plastics, glass, and so on.
This law has made automobile manufacturers think more carefully about the kinds of materials that go into automobiles and how those materials are used.
Recycling is a new way of looking at our use of the earth’s resources.
To solve the problems of both supply and disposal, we should ____.
选项
A、raise the price of natural materials
B、reduce glass and metal production
C、produce more and more materials
D、reuse the materials that have been used
