Nowadays, air pollution is becoming one of the most major concerns throughout the world. There are several causes such as burning fossil fuels, emission of pollutants, smoking and transportation which contribute in developing air pollution. These causes may lead to several difficulties on the environment, such as health problems, acid rain and global warming.
One of the most important effects of air pollution is bringing on breathing problems, such as asthma. Since children are more active than elderly people and breathe more rapidly and take more air into their lungs, they are so affected by air pollution. In addition, some people breathe through their mouth, not through their nose, and the mouth is not able to filter the pollutants as well as the nose. It is obvious that establishing programs to improve air quality has a considerable impact on prevention of breathing problems.
Acid rain also causes extensive damage to plants, water resources, and natural ecosystems. For example, ecosystems are seriously affected by acid rain. Moreover, acid rain can endanger the animals’ life. It can also destroy some of animals’ species. In addition, acid rain damages agricultural products and often makes heavy losses. It can also damage the stonework of houses, historical buildings and even statues. Using renewable energy sources such as wind and sun for generating electricity is one of the most effective ways to prevent acid rain.
Another cause of air pollution is global warming. Global warming is due to increase of gases which trap the heat of sun like CO2, changes in weather, excessive use of fossil fuel, emission of industrial pollutants. The effects of global warming may be very dangerous. It can be the cause of a number of natural disasters, such as floods, draughts, jungles fires, hurricanes and earthquakes. Global warming can be reduced through establishing some laws to reduce air pollution. In addition, planting
