Welcome to the Probiotic Revolution. It's what you and I were never taught in school about the startling link between your body's intestinal flora and your ability to prevent serious illness, to add vital years to your life, and to enjoy a dramatically higher quality of life right now.
Bacteria are the simplest, smallest, and most abundant organisms on the planet.
One of their most important roles is decomposition. Without bacteria, organic carbon, found in dead and rotting organisms, would deplete the carbon dioxide in the atmosphere. Without carbon dioxide, photosynthesis could not occur and no food could grow. Bacteria are also important for everyday functions of the body including digestion. So, as you can see, bacteria are vital to human survival.
