Oxygen Is One Of The Most Important And Abundant Elements On Earth

577 words - 2 pages

Oxygen is one of the most important and abundant elements on Earth. About 46 percent of the Earth's crust is oxygen. It is colorless and odorless and makes up about 20.95 percent of the atmosphere by volume. Oxygen exists in water as part of water molecule, in the atmosphere as a gas, in the Earth's crust and in an enormous variety of rocks and minerals. It can also be released from the plants through photosynthesis. Moreover it is very essential for life and is part of almost every biological molecule in our bodies. Without it, human life simply could not exist. Humans can live for weeks without water, and go without food for months, but without Oxygen, life could only carry on for a matter of moments.About 90% of the body's life energy is created by Oxygen.

This condition is known as "hypoxia". It has been shown that any type of stress to the body will bring oxygen deficiency. TOXIC STRESSES (toxic...
