Did you know that the microbes on just one of your hands outnumber all of the people on the earth? Or that millions of microbes could fit into the eye of a needle? These one-celled, living organisms are too small for us to see without a microscope, yet they live in the air, soil, water, and even in our bodies. We constantly interact with them, even though their world is completely beyond our senses.
