Ways to prevent air pollution air pollution, responsible for triggering many health problems, is mostly caused due to burning of fossil fuels. the most effective ways to prevent air pollution are minimizing the use of fuels, servicing vehicle regularly, saving energy, using alternative energy, and recycling materials amongst others. causes and effects of air pollution air pollutants, either present inside the house (indoor pollutants) or outside (outdoor pollutants), are hazardous to humans. the major pollutants are sulfur dioxide, carbon monoxide, carbon dioxide, nitrogen oxides, and particulate matters. among the different causes of air pollution, burning of fossil fuels such as coal, petroleum, and gasoline is found to be the main contributing factor. fossil fuels are used in all major industries, including the automobiles, jet planes, manufacturing industries, power plants, petroleum refineries, etc. the effects of air pollution on the human health are many. to mention a few, it triggers respiratory ailments and irritation of eyes and throat. the common symptoms observed after exposure to a high level air pollution are chest tightness, burning eyes, and cough. those with certain medical conditions like heart disease and asthma are more susceptible to the hazards of air pollution than others. as expected, the effects are more serious in children; prolonged exposure to air pollution can lead to earache, bronchitis, and asthma. different ways to prevent air pollution vehicle care: timely servicing of the car helps to keep it in a good condition, and also minimizes fuel exhaust. driving the car at an average speed and turning off in traffic are the thumb rules to save fuel. make sure to use unleaded petrol and opt for regular pollution checking of your car. public transport: whenever possible, try to travel by public transports. this helps in two ways; prevents air pollution and increases public income. if you are going to a nearby place, go by walking or use a bicycle, instead of using your vehicle. the objective is to minimize the use of fuels as far as possible. alternative energy source: another effective way to prevent air pollution is to use alternative energy sources such as solar energy, hydroelectric energy, and wind energy. nowadays, sophisticated technologies such as wind turbine, solar water heaters are introduced to generate electricity and other energy forms for household uses. saving energy: saving energy will, of course, help to prevent air pollution. switch off the lights, fans, air conditioners, televisions, and other appliances, when not in use. you can also share a room with others when the air conditioner or fan is on, instead of switching them on in every room. minimize air pollutants: always try to minimize smoke emission, as it contributes a lot to air pollution. one way is to compost dried leaves and kitchen waste, instead of burning them. composting will also give you organic fertilizer for your garden. other tips include replacing old wood stoves or gas furnaces, avoiding solvents, and most importantly, do not smoke in the home. recyclable materials: recycling is a simple approach to reduce pollution in two ways; save energy which is required for disposing and minimize the pollutants released during manufacturing. the list of recyclable materials include plastic bottles, aluminum cans and utensils, paper, craft papers, cardboard, corrugated boxes, and glass bottles. smart purchasing: remember to carry paper bags and minimize using plastic bags. while buying the products, always choose air-friendly and recyclable products that will minimize the emission of pollutants. also, shop for only energy-efficient appliances that use less packaging. lastly, buy rechargeable batteries for frequently used devices. social awareness about air pollution is the most essential step to be taken for the prevention of air pollution. awareness programs and/or advertisements should be encouraged, so that people understand the potential health hazards of pollution. improvement of transport facilities and proper use of land for the sake of social benefits are equally important for controlling air pollution.
