Are you concerned about the quality of the air you breathe? Air pollution, a by-product of our modern age, is an ongoing problem in many parts of the United States.
According to the American Lung Association’s annual State of the Air Report, 147.6 million people – 47% of the nation – live in counties with unhealthy levels of particle and ozone pollution. That is an increase of 16 million from last year. One of the worst polluted cities is Los Angeles, CA, where the air is considered unhealthy 120 days of the year, on average.

Particle pollution comes from a variety of sources, but chief among them are industrial emissions and vehicle exhaust. When these emissions react with the U.V. light of the sun, they form ground level ozone. Both of these pollutants are known to have serious negative impacts on human health. They especially affect individuals suffering from respiratory and cardiovascular diseases.
While air pollution continues to be a serious challenge in this country, the report also notes the fact that our air – overall – is cleaner now than it has been in previous decades. This is largely due to the regulations put in place by the Clean Air Act.
