Air and Water Pollution | Introduction
Introduction
Air or water that is contaminated with impurities is described as pollutedAir or water that is contaminated with impurities.. The contamination is the pollutionThe contamination of the natural environment, usually through human activity.. Directly or indirectly, the overwhelming majority of pollution results from human activity, yet nature can also release pollutants. Pollution usually is in the form of gas, liquid, and solid materials; it results from anything that alters the natural environment, such as a temperature shift and noise. Air and water pollution has become a significant problem since the growth of cities, industry, and travel in the late nineteenth century.
All life on Earth depends on air and water to live and grow. Pollution of these substances harms and destroys plants, animals, and microscopic organisms. It causes health problems and death in humans. Pollution upsets the natural cycles on which all life depends, causing a ripple effect that can harm organisms hundreds of miles away from the pollutant. For example, pollutants in a body of water can harm the sea life and poison the plants that depend on the water. In turn, surrounding animals that depend on the plants for food and shelter, such as birds, will need to either move to another location or die. Water and air pollution also destroy Earth's natural beauty.
