Blog 4: Acid Rain and Assorted Air Pollutants


Acid rain is an invisible byproduct of air pollution and can be extremely destructive. The effects of acid rain can be rusting of iron, erosion of marble or limestone, destroying car paint, and deterioration of plant life, etc. It is usually caused by coal-burning power plants, industrial processes, and automobiles, which emit sulfur dioxides, nitrogen oxides, and carbon dioxides into the atmosphere. Acid rain can come down in any form of precipitation. Since it is invisible, people can only see the effects of acid rain happening, rather than the acid itself contained within the precipitation. The World Health Organization sets limits of air pollution and more than about one hundred million people live in areas of Latin America, such as Paraguay and Rio de Janeiro, that exceed the WHO’s limitations. For example, in Mexico City and Sao Paulo, air pollution has been linked to respiratory problems and deaths of adults and children. In areas of bad pollution, there is a greater chance of acidic rain damage. For example, every year over six billion dollars of damage is caused by acid rain in the United States alone. Since the United States is a country with pollution regulating laws and it has such a high amount of annual damage being done, how much greater damage is being done in countries that aren’t as developed and do not have regulation laws? As less developed countries (LDC’s) such as those in Latin America begin to industrialize, there will be a rise in acid rain problem. This is inevitable unless highly developed countries (HDC’s) such as the United States help improve the LDC’s industrial technology to minimize not only pollution but also the overall environmental impact they are having. If HDC’s do not choose to help LDC’s develop in a more sustainable manner, then the people of LDC’s will have to “deal” with the environmental destruction being caused by acid rain on their own. This is very much a sociological problem, affecting the people of Latin America and the way they live. And although I’ve used examples of Latin American cities, acid rain occurs everywhere, especially in areas of much advanced human activity.
