Air Pollution.

Air pollution is made up of many kinds of gases, droplets and particles that reduce the quality of the air. Air can be polluted in both the city and the country. In the city, cars, buses and airplanes may cause air pollution. In the country, trucks and cars driving on dirt or gravel roads, rock quarries and smoke from wood and crop fires may cause air pollution. Air pollution can cause some symptoms for example; irritate the eyes, throat and lungs, burning eyes, cough and chest tightness. Different people can react very differently to air pollution. Some people may notice chest tightness or cough, while others might not notice any effects. Because exercise requires faster, deeper breathing, it may increase the symptoms. People with heart disease or with lung disease, such as asthma, may be very sensitive to air pollution exposure, and may notice symptoms when others do not. Air pollution is bad for your health. Fortunately for most healthy people, the symptoms of air pollution exposure usually go away if the air quality improves. However, some people are more sensitive to the effects of air pollution than others. Children probably feel the effects of lower levels of pollution than adults. They also experience more illness, such as bronchitis and earaches, in areas of high pollution than in areas with lower pollution. People with heart or lung disease also react more severely to polluted air. Their condition may come to the point that they must limit their activities. To protect yourself and your family from the effects of air pollution you must follow these following steps. First, stay in your house as much as you can during days when pollution level is high. Second, if you have to go outside, try to limit your outside activities to the early morning or after sunset. This is important in high ozone conditions because sunshine increases ozone levels. Third, don't exercise outside when air quality is unhealthy. The faster you breathe the more pollution you take into your lungs. In conclusion, people must know about what's going on in this world. If we keep on polluting the air, our children might not breathe normally. Life on earth might not be possible. Earth will be just like any other planet. Human can't live without air, without healthy clean air there will be no life on earth. Save the planet, save the environment, but mostly save the future
