Los Angeles Pollution
I am from Los Angeles, and after reading this Chapter and seeing how many times the city's name was used I decided to do research. An article in the Huffington Post talks about the most dangerous U.S. cities in regards to air pollution. Many of the cities listed, Los Angeles included, were located in California. Despite the efforts to improve air quality in Los Angeles, it had the most ozone pollution in the country in 2009.

It is interesting that all of the cities on this list have relatively flat topography and frequently experience hot and dry conditions. Most of these cities (perhaps excluding LA) are not known to be extremely industrial (or to be huge urban centers), and do not have overwhelmingly large populations compared to cities that did not make this list. Perhaps this speaks about the influence that topography and climate have on air pollution as compared to other factors such as the scale of industrial or agricultural output. Maybe this is something that needs to be taken into account when deciding where to locate centers of industry and agriculture. Areas with topographic/climatic factors that pre-dispose them to higher levels of air pollution might want to restrict/prohibit new such types of activity.
