Program Overview
|
|
|
We are surrounded by a world that can only be seen with the aid of
magnification. Sometimes the members of this microscopic society are helpful,
like the bacteria in our intestines that aid in food digestion. Other times
they are harmful, like the AIDS virus, which compromises the immune system.
Some are instrumental in the decomposition of dead material, like the dust
mites that devour dead skin flakes. And they are everywhere, including on the
hair on our skin, among the fibers of our clothes, in the books on our shelves,
and on the plants in our yards. This program reveals some of the billions of
practically invisible organisms that live on, in, and around us.
