For example, exhaust from automobiles causes a large percentage of all air pollution. But automobiles provide transportation for millions of people. Factories discharge much of the material which pollutes the air and water, but factories give employment to a large number of people. Too much fertilizer or pesticide can ruin soil, but fertilizers and pesticide are important aids to the growing of crops.
