阅读下面短文，根据短文内容，判断短文后所给句子的正(T)误(F)。

The comforts and conveniences of modern life have brought with them problems that did not exist in the days of simpler living． Machinery which operates on electricity made by burning coal or petroleum is used to process raw materials taken from the earth． Gases from the burning fuels are sent into the air． Wastes from making raw material into finished products are sent both into the air and into the water．

As a result of these and of other pollutants some lakes and rivers have become so contaminated that the fish in them die． Besides the dangers to health from breathing polluted air, the waste gases have effects on the upper atmosphere, which may endanger life on earth．

These threats, as well as the depletion (耗尽) of natural resources (such as fuels, forests, and soil) by carelessly wasteful use, have worried scientists and other thoughtful people．

Such persons are also disturbed about the effects of chemical fertilizers and of poisons which farmers use in order to destroy insects and weeds． Above all, they are alarmed at the interference (冲突) with the natural balance of the environment, and its possible consequences (结果)．

As a result, there have been attempts to alert the public to these dangers and to control pollution, as well as to reduce the wasting of natural resources． One way of bringing these problems to the attention of the public is the yearly celebration of Earth Day, which began in 1970． There are also articles and books by environmentalists and organizations interested in ecology, the study of the interdependence of organisms and the environment．

The United States government’s Environment Protection Agency is studying various ways of avoiding danger to the population． For example, its scientists are making investigations to find out whether water pipes made of certain materials can have chemical effects on the water they transport, which might induce (引起) cancer or other diseases． By these and other antipollution studies and regulations, it is hoped that the environment can be prevented from deteriorating (恶化) further．
