Air pollution levels may be reduced at home and the office by conserving energy, planting deciduous trees, recycling paper and plastics and keeping automobiles maintained. Air pollution stems from many sources, which makes it difficult to prevent it from entering into the atmosphere altogether.
At home, residents can conserve energy (and save money too) by turning off appliances and lights upon leaving a room. Most electricity comes from fuel plants and refineries, which operate by burning coal and other fuels. The toxic smoke produced during these processes contributes significantly to air pollution levels and releases harmful chemicals such as nitrogen oxide, sodium dioxide and carbon dioxide into the surrounding air.
Using warm or cold water when showering and washing clothes also helps lower air pollution levels because hot water requires more energy for generation. In addition to homes, cars contribute to air pollution levels too. Motorists can reduce their automotive pollutant footprints by keeping tires properly inflated and aligned, which makes cars more efficient and therefore cuts down on fuel consumption, and filling gas tanks during the cool morning or evening hours in the summertime. Doing so cuts down on evaporation produced during the fueling process, which leaches into the air.
