We all need it like air as there is no life without it. We all know that oxygen is what we need, and this is true, but the question is how much of it is necessary for normal functioning of the body. Apparently much less than we think we need. And an even more bizarre paradox is that it is the carbon dioxide that our lungs produce and we expel as soon and as much as we can, that practically helps to absorb oxygen and utilize it in the body.
Carbon dioxide is the fundamental nutrition of every life form on Earth.
It acts as the main regulator of all functions in the organism, as it is the main internal environment, regulating activities of all vitamin and fermented substances of the organism. It is the vitamin of all vitamins, and is the basic food product of all life forms on Earth. Plants absorb carbon dioxide from the air. Animals feed on plants and humans feed on both of these. That means that it would be much more veneficial for us to keep carbon dioxide in our body longer and in greater quantity.
