Air, by the definition, is the invisible gaseous surrounding the earth, which doesn't really explain what air exactly is. So I'll tell you what air actually is.

First of all air is made out of different types of gases. 78.09% nitrogen, 20.95% oxygen, 0.04% carbon dioxide and many more gases. Theses stats can vary depending on your location. For example, carbon dioxide stat is higher if you are in a polluted area such as Iran and China. Oxygen stat could be higher in the countryside. Atmospheric composition also varies by altitude. Higher altitude leads to lower level of oxygen, which makes people harder to breathe.
Air is what most people take it for granted, which we should never do. Humanity have been destroying our planet and the most serious problem is air pollution. Leading to increasing the level of carbon dioxide, greenhouse effect, and many more serious outcomes. Studies tell that if the level of air pollution continues, our planet will eventually become to the unsuitable conditions for humans to live in. Therefore we need to take responsibility and I'll be going through how we should take responsibility to this problem, in my next blog.
