read the passage shown here. which options support the thesis statement, \the growth of chemical pollution is a serious problem with far - reaching effects\? select all that apply.
the problem posed by chemical pollution has grown very serious in recent years, both because of the growth of heavy industry and because of an overly casual attitude in industrialized countries. chemicals are released into both the air and into water; therefore, their effects are far reaching. air pollution is a major problem in the worlds cities. in mexico city, oxygen is sold routinely on street corners for patrons to inhale. cities such as new york, boston, and philadelphia are known as gray - air cities because most of the air pollutants are sulfur oxides emitted by industry. cities such as los angeles, however, are called brown - air cities because the air pollutants undergo chemical reactions in the sunlight to form smog. disposing of chemicals into the water, a \flushing it down the sink\ approach, doesnt work in todays crowded world. there is simply not enough water available to dilute the many substances that the enormous human population produces continuously. lakes and rivers throughout the world are becoming increasingly polluted with sewage, fertilizers, and insecticides that wash from the land to the water in great quantities.
