Oxygen On Earth, oxygen is produced by green plants on the Earth as well as by plankton in the ocean, both as a result of the process of photosynthesis in which carbon-dioxide is transformed into oxygen and carbon compounds. Today oxygen constitutes 21% of the atmosphere, but it is also known that it was at a much higher concentration in the past. As the most important element of life, oxygen provides the necessary energy for every human cell. After being used, oxygen is released from the body in the form of carbon dioxide or water molecules, which are consumed by green plants and ocean microorganisms to produce new oxygen molecules. In this cyclical process, these newly produced oxygen molecules are what we breathe while the carbon compounds are incorporated into the foods we eat. A deficit of oxygen in the human body leads to a lack of energy, imbalance, damage, disease and, finally, death of the involved cell, tissue, organ or the entire organism that is being deprived of its oxygen needs. Many diseases are primarily caused or complicated by hypoxia, which is a decreased concentration of oxygen in the tissue or body. Without oxygen, or when it is at a very low concentration, human cells lose their energy and have no strength to carry on their normal functions, which ultimately leads to an additional imbalance as well as damage. Without energy, the affected cell is exposed to internal or external pathogenic signals that lead to the colonization by microorganisms, mutation or degeneration. When provided with a higher concentration of oxygen, human cells regenerate their energy and are able to recuperate and return to their natural functions that will finally lead to the healing and regeneration of affected tissues, organs or the entire organism. Activated Oxygen In nature, activated oxygen is usually formed in the upper atmosphere by photon absorption, or in the lower atmosphere by electrical discharge. This is a reaction in which absorbed energy breaks apart the molecular oxygen bond and converts a molecule of oxygen into active oxygen atoms. When three atomic oxygen molecules come together, they form the molecule we call ozone. Being an unstable gas, the life of an ozone molecule is about 20 minutes, depending on the temperature, and then it reverts back to oxygen. Tri-atomic oxygen is second only to fluorine as the most powerful oxidizer or oxidant in the world, which is why it's the most powerful, natural sanitizer readily available. Ozone breaks down most chemicals into their most basic, naturally occurring component parts. As more time passes, these component parts are eventually broken down into H2O, carbon dioxide, sulfur, nitrogen and oxygen. The breakdown of ozone leaves no toxic by-products or residues and is non-carcinogenic.
