AnswerThere are a lot of bacteria all over the world that affect the environment and the creatures that live within them, including humans. Estimating their number, though, is both difficult and largely meaningless. For example, even a simple infection on one person (such as an infected cut), may contain billions of separate bacteria. trying to estimate quantities worldwide would involve numbers that are simply too large to be useful.
