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.
