This is part one of a two posts. This one on Air and what it is and some history and statistics. The second will be about air pollution and some thoughts on it and some ideas on how to help prevent it.
Aristotle (Born: 385 BC; Died: 322 BC) was a interesting person and a father of modern Astronomy. He also furthered the idea of the elements: Earth, Wind, Fire, and Water. I say this little tidbit of information because I do not think Aristotle could think that today, 2020, how much of impact these elements have on our lives. Especially one in particular, Air.
I wonder what Aristotle would think about how much we know about what air is an how much makes up the Earth’s atmosphere. According to the National Aeronautics and Space Administration (NASA)  air is…
78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.
I have to say also we can do a lot with air, good and bad. For the most part the positive about air it keeps us alive and well. You can live only about three minutes without it. But, What happens if we damage the air or pollute the air which keeps us alive? Good question!
This is were my title of the post, Air, comes in. I want to explore air and air pollution.
Some statistics on air…
“Around 91% of the world’s population lives in places where air quality levels exceed WHO limits.” 
“The EPA has identified six pollutants as “criteria” air pollutants because it regulates them by developing human health-based and/or environmentally-based criteria (science-based guidelines) for setting permissible levels. These six pollutants are carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution (often referred to as particulate matter), and sulfur oxides.” 
“…air pollution can impact mental health, worker productivity and even stock market performance.” 
All this is to show how much of a impact air has on us and how much of a impact air can be a issue for us at the same time. We should value air not take it for granted. As Evel Knievel said…
I love the feeling of the fresh air on my face and the wind blowing through my hair.
Be on the look out for the second post soon.
