Many people enjoy getting out in nature. From listening to the birds sing to watching the squirrels scamper, nature gives us many joys. Another reason people like getting out in nature is breathing the fresh air. Being indoors in an office environment all day can be stifling. Taking a big deep breathe of fresh air invigorates us to conquer our days. Luckily for us, our air quality in Texas is good. We don’t have to worry about acid rain, contaminants, or breathing in coal dust. However, it wasn’t that long ago that air quality was taken for granted and ignored — until the ill effects of breathing in dirty air began to affect our health and wellbeing.

Good air quality is only a recent concern because it’s a relatively recent problem. In ancient times up until the Middle Ages, people lived in small villages and townships. Big cities didn’t really exist as the world population was low compared to what it is today. It wasn’t until the end of the Middle Ages as cities began to grow that air pollution grew worse. The problem began when coal became the predominant form of energy. In England, air pollution was well documented beginning in the 16th century from coal burning pollutants. As the Industrial Revolution hit full swing in the 18th and 19th century, smog (smoke and fog) became dangerous in many big cities all over the world. Pollution caused many deaths, and it never seemed to get better. However, coal wasn’t the only culprit. With the advent and growth of automobiles in the early 20th century, car emissions only caused the air quality problems to escalate.


London, as one of the leaders in the Industrial Revolution, suffered greatly from poor air quality throughout the 18th, 19th, and the beginning of the 20th century. In the autumn months, the weather in London was calm, causing smoke particles to congregate in London. Industrial pollutants gave this fog a yellow-black color. The word smog was soon coined to describe these plumes that hovered over the city of London for days. London became famous for its smog, becoming a bona fide tourist attraction similar to Big Ben and Trafalgar’s Square.

Four thousand people died in the Great London Smog of 1952 where for five days a smog cloud hung over London as smoke and sulfur dioxide levels peaked in the city. Finally, the British took action, which began a wave of air pollution laws passed beginning in 1956 that has helped clean up the air of London today.

The Clean Air Act was passed in the United States in 1963 in response to our worsening air quality. Since then, our air quality has gotten much better as the connection between clean air and our health has become abundantly apparent.
