Air Pollution At My College (1)

Air is the ocean we breathe. Air supplies us with oxygen which is essential for our bodies to live.

My college actual situation:
- about 12.000 Students
- vehicles: 3779
- cars: 2140
- motorbikes: 1639
- Smoking is not allowed at the university area, but: some students/employees/lectures smoke secretly, or they smoke somewhere outside (nearby the university)
- burning of waste/garbage everyday in the surrounding of the college (across the street/near the Boarding Houses)

Air pollution is perhaps Indonesia's most severe environmental problem. According to an official at the World Bank office in Jakarta, "air pollution imposes costs of at least $400 million on the Indonesian economy every year." It also has very a serious impact on public health. For example, inflammation of the respiratory tract, which is directly linked to air quality, was the sixth leading cause of death in Indonesia (after accidents, diarrhea, cardiovascular disease, tuberculosis, and measles).
Motor vehicles are one of the chief sources of air pollution in Indonesia. Between 1995 and 2001, the number of vehicles in Indonesia grew from 12 million to almost 21 million. Many of these vehicles are motorcycles or scooters, which lack the catalytic converters required for cleaner emissions. Moreover, almost no motor vehicles in Indonesia use unleaded gasoline. Instead, the vast majority of these vehicles rely on either leaded gasoline or diesel fuel, leading to unhealthily high concentrations of airborne lead.

What is air pollution?

Air pollution means the presence in the outdoor atmosphere of one or more contaminates, such as dust, fumes, gas, mist, odor, smoke or vapor in quantities, of characteristics, and of duration, such as to be injurious to human, plant, or animal life.
The two main sources of pollutants in urban areas are transportation (predominantly automobiles) and fuel combustion in stationary sources, including residential, commercial, and industrial heating and cooling and coal-burning power plants. Motor vehicles produce high levels of carbon monoxides (CO) and a major source of hydrocarbons (HC) and nitrogen oxides (NOx).

Effects:

Human:

Air pollution can affect our health in many ways with both short-term and long-term effects. Different groups of individuals are affected by air pollution in different ways. Some individuals are much more sensitive to pollutants than are others. Young children and elderly people often suffer more from the effects of air pollution. People with health problems such as asthma, heart and lung disease may also suffer more when the air is polluted.
Examples of short-term effects include irritation to the eyes, nose and throat, and upper respiratory infections such as bronchitis and pneumonia. Other symptoms can include headaches, nausea, and allergic reactions. Short-term air pollution can aggravate the medical conditions of individuals with asthma and emphysema.
Long-term health effects can include chronic respiratory disease, lung cancer, heart disease, and even damage to the brain, nerves, liver, or kidneys. Continual exposure to air pollution affects the lungs of growing children and may aggravate or complicate medical conditions in the elderly.
