From the time a baby enters the world, the first need of it’s precious body is met. Oxygen fills it’s lungs as it breathes it’s first breath. Of course, this continues to be the most important need in life and one of two main topics in this lesson.
All that needs to be done to see the importance of oxygen is to cut off it’s supply for just a few minutes. Life can remain without food for a few weeks, without water for a few days, but only a few minutes without oxygen. The continual process of in taking life and breathing out carbon dioxide fills the trillions of cells with life.
The length of human life depends on the quality of air that is breathed in. Air can determine the level of health that is attained though out life. More facts about how oxygen is vital will be presented shortly but a look at the harmful affects of bad air needs some attention.
