Where I can find a place on earth that is liveable that isn't bacteria infested? Everything in the world is crawling with microorganisms. There are bacterias in the air, water, ground. There are bacterias even living in extreme conditions like super salty, super hot, and so forth super cold. The bacteria in the air's proof is water vapor. Humid is the moistness of a place. The only thing that isn't bacteria infested that I know of if a newborn baby but after that is inside the mother's stomache, the mother's bacteria will colonize that. Yogurt even have bacteria. Everything that is food are covered with bacteria too. Anything you drink is filled with bacterias too. How can I avoid every bacteria in the world? I cannot exactly kill every bacteria near me since there are way too many bacterias.
