Air Pollution is one of the most worrying problem. This problem started during the industrial revolution, which brought about many positive changes to the world; better transportation, cheaper products, and a better life. However, these beautiful changes led to pollution on other hand. At the beginning of the industrial revolution, no one paid any attention to the problem of pollution. As the science progressed, people started to realize this problem. Each year air pollution is the cause of millions of human deaths, and even larger numbers of respiratory, circulatory, and cancer-related disease occurrences
Air pollution arises from many sources. The most common and widespread air ...view middle of the document...
These molds create spores that can go inside a human body and cause many complications. According to the American Lung Association, mold triggers allergic reactions, including asthma. A study by the Mayo Clinic states that mold is the cause of nearly all chronic sinus infections. It can lead to serious complications, including breathing difficulties, memory and hearing loss, and bleeding of the lungs.
As serious as the indoor pollutants are, they are minimal compared to the outdoor pollution. This includes pollution from factories to volcanoes. Gases are released in the air from the fissile fuel burned by the factories ships, automobiles, ships, and trains. Every industry process exhibits its own patterns of air pollution.
Both sulfur oxides dissolve in atmospheric water droplets to form acidic solutions that can be very damaging when distributed in the form of rain. It is thought that sulfuric acid is the major cause of the acidity in acid rain, which is not only damaging forests in the Northern Hemisphere but also causing fish, to die off in many northern lakes as well. Acid rain is also corrosive to metals, limestone, and other materials. The possible solutions to this problem are expensive because of the difficulty of removing sulfur from coal and oil before they are burned.
Another major environmental problem caused by air pollution is global warming or the "greenhouse effect". The greenhouse effect is caused by solar energy being trapped by CO2, Methane, Ozone (O3), Nitrous gas, and Chlorofluorocarbons (CFCs) that are in the air. The solar energy comes into the atmosphere as light, it hits the Earth, looses some of its energy and becomes heat. Because the heat does not have as much energy it can not penetrate back through the blanket of gases. The Earth has a natural greenhouse effect caused by the CO2 in the atmosphere. If we didn't have this natural greenhouse effect, the Earth would be too cold to live on.
Carbon dioxide is not as lethal as carbon monoxide, sulfur oxide, or nitrogen oxide, however Carbon dioxide (CO2) is one of the major pollutants in the atmosphere. Major sources of carbon dioxide are fossil fuels burning and deforestation. Industrial countries account for 65% of carbon dioxide emissions with the United States and Soviet Union responsible for 50%. Less developed countries, with 80% of the world’s people, are responsible for 35% of carbon dioxide emissions, but they may contribute 50% by 2020. Carbon dioxide emissions are increasing by 4% a year. In 1975, 18 thousand million tons of carbon dioxide was released into the atmosphere, but the atmosphere showed an increase of only 8 billion tons. The ocean waters contain about sixty times more carbon dioxide than the atmosphere. If the oceans can no longer absorb this much carbon dioxide, then more carbon dioxide will remain into the atmosphere. As water warms, its ability to absorb carbon dioxide is reduced.
