The five basic elements of life are: oxygen, hydrogen, carbon, nitrogen and sulfur. All of these elements have their own role in all biological processes. Of these five basic elements of life, oxygen has one exceptional property:
Oxygen atoms can be easily bound to other molecules. That is why there is oxygen practically everywhere: there is hardly any material on earth which is not partly made up of oxygen.

There is nothing as important as oxygen in life. Oxygen was discovered already in 1773. Oxygen has been scientifically researched, especially in the field of medicine. It was discovered how serious and partly life-threatening the consequences of a lack of oxygen can cause in the human body.

Oxygen is our metabolism. Our body receives most of its oxygen through respiration. Oxygen is absorbed into the blood circulation in our lungs. Hemoglobin can tie oxygen and take oxygen to the billions of our cells in our body. Our cells need oxygen to develop energy and warmth. The more energy our body uses, the more oxygen it needs. In addition to nutrition, we need oxygen sufficiently and continuously for our body to function and for every single cell in our body to keep healthy and functional.

Oxygen has also another important role in our body. Our immune system uses oxygen. Oxygen can destroy illness-causing electrons which live in an oxygen-free environment. This "destruction system" can destruct illness-causing bacteria, viruses and mycosis.

The main oxygen suppliers are rain forests and sea plankton. Today, there is 30% less oxygen in the air than one hundred years ago. Increasing air pollution, increasing rain forest cutting, pollution of seas and rivers are some of the reasons for the decrease in oxygen content of the air.
