Pollution is a "dirty" word. To pollute means to contaminate—topsoil of something by introducing impurities which make【B1】______ unfit or unclean to use. Pollution comes in many forms. We see it, smell it,【B2】______it, drink it, and stumble through it. We literally lived in and breathe pollution, and not surprisingly, it is beginning to【B3】______our health, our happiness, and our civilization.

Through the uncontrolled use of insecticides, man has polluted the land, killing the wildlife. By【B7】______sewage and chemicals into rivers and lakes, we have contaminated our 【B8】______water. We are polluting the oceans, too, killing the fish and【B9】______depriving ourselves of an invaluable food supply.
Part of the problem is our exploding【B10】______. More and more people are producing more wastes. But this problem is intensified by our "throw-away" technology. Each year Americans【B11】______of 7 million autos, 20 million tons of waste paper, 25 million pounds of toothpaste tubes and 48 million cans. We throw away gum wrappers, newspapers, and paper plates.

Instead of repairing a toaster or a radio, it is easier and cheaper to buy another one and discard the old, even 【B13】______95 percent of its parts may still be functioning. Baby diapers, which used to be made of reusable cloth, are now paper throw-aways. Soon we will wear clothing made of【B14】______: "Wear it once and throw it away" will be the slogan of the fashionable-consciousness.
Where is this all to end? Are we turning the world into a gigantic dump, or is there hope that we can solve the pollution problem?【B15】______, solutions are in sight. A few of them are positively ingenious.
