Environmental pollution is a term that refers to all the ways by which man pollutes his surrounding. Man dirties the air with gasses and smoke, poisons the water with chemicals and other substances, and damages the soil with too many fertilizers and pesticides. Man also pollutes his surrounds in various other ways. For example, people ruin natural beauty by scattering junk and litter on the land and in the water. They operate machines and motor vehicles that fill the air with disturbing noise. Nearly everyone causes pollution in some way.

Environmental pollution is one of the most serious problems facing mankind today. Badly polluted air can cause illness, and even death. Polluted water kills fish and other marine life. Pollution of soil reduces the amount of land available for growing food. Environmental pollution also brings ugliness to man's naturally beautiful world.

Water pollution reduces the amount of pure, fresh water that is available for such necessities as drinking and cleaning, and for such activities as swimming and fishing. The pollutants that affect water come mainly from industries, farm, and sewerage systems. Industries dump millions of tons of waste products into bodies of water each year. These wastes include chemicals, wastes from animal and plant matter, and hundreds of other substances. Wastes from farms include animal wastes, fertilizers, and pesticides. Most of these materials drain off farm fields and into nearby bodies of water. Sewerage systems carry wastes from homes, offices, and industries into water.

People, however, may differ in what they consider to be a pollutant, on the basis of their assessment of benefits and risks to their health and economic well-being. For example, visible and invisible chemicals spewed into the air or water from a plant nearby pose a danger to the people nearby and other animals and plants. However, if the installation of expensive pollution controls leads to the reduction of productivity, the unemployed might feel that the risks from polluted air and water are minor weighed against the benefits of profitable employment. The same level of pollution can also affect two people quite differently --- some forms of air pollution might be a slight annoyance to a health person but life threatening to someone with emphysema or another respiratory disorder
