Journal of Occupational and Environmental Medicine. (2014, September 8). Air pollution may affect levels of obesity-related hormone. ScienceDaily. Retrieved November 23, 2014 from www.sciencedaily.com/releases/2014/09/140908120012.htm
To figure out whether higher exposure to traffic-related air pollution cause higher levels of obesity-related hormone, Gregory A. Wellenius, ScD, of Brown University and his colleagues decided to investigate the issue. They did this by measuring the traffic-related air pollution of Boston and the blood leptin levels of some of 765 adult people. Although the result can’t prove any casual link of the issue, the link between the black carbon exposure and leptin levels might help.
It is reasonable to have a study of whether or not air pollution causes higher levels of obesity-related hormone. Since there are numbers of consequences an air pollution is able to produce, the issue relating to the article is an addition. In theory, this article and any other articles relating to air pollution interpret the fact that air pollutants are dangerous that if no immediate action was done, all the people will be having numerous diseases that results from air pollution.
I agree that this could be a major issue, but this might be correlation and not causation. Places with worse air pollution are likely to be resided in by people who are closer to the poverty line, with less money. Additionally, this is exacerbated by the fact that legislature preference is often given to zip codes with more money, especially since they pay more taxes and therefore have more ability to improve infrastructure that could affect air pollution. Lastly, people living closer to the poverty line tend to be more obese on the whole because fast food is cheaper, and easier if they are working long shifts to make ends meet. So while this could be linked, since bad health makes it easier to gain weight, and air pollution causes bad health, it could also be reliant on many other factors.
