Science Netlinks: What's a Germ?

What do germs, also called microbes, have to do with humans? Humans (and plants) are a place for germs to live. Think of it this way: humans need certain things to live, like oxygen, food, and water. If you take a human out of this safe, earthly environment and sent him or her to say, the moon, without food, water, and oxygen, he or she would not survive. Germs also need a certain environment in order to survive.
