In this article I read about American cities with the dirtiest air. 44% percent of americans are living in areas that have particle pollution. Fortunately, compared to last years results, there has been an improvement, since last year 3% of the population moved out of the area. However, cities that have high level of particle pollution in the air have solid and liquid particles found in the air, breathing in this polluted air can lead to serious health issues. Due to the heat, short-term particle pollution is mainly an issue in the West, Los Angeles has the worst ozone pollution. Air pollutants are responsible for many health issues. For example, 3.7 million premature deaths worldwide, causing lung cancer, chronic obstructive lung disease, and heart disease. Also, low-income communities where most minorities live are mostly exposed to these harmful air pollutants. The main source of these air pollutants come from power plants, wild fires, factories and more. I found this article very interesting because it is involved with air quality and why is it important to us and why we should keep improving our air. Also what I found interesting was, people with lower income are more exposed to these pollutants.
