Managing wildlife is simple. A kid could do it.

Earth abounds with many, many different kinds of living things: butterflies, mushrooms, starfish, eagles, sharks, redwood trees, caterpillars, ferns, amoebas, seaweed, lions, and tigers, and bears ("Oh my!"). The list goes on and on. Nearly one and a half million different species* of living things are known, and millions more are yet to be discovered in the depths of Earth's oceans and forests.

Scientists use the words "diversity," or "biodiversity," to describe different aspects of the variety of life forms all around us. Species diversity describes the number of different species in a region or in the world. Genetic diversity describes the differences within a single species. Classification is the method we use to keep track of all the different kinds of living things and how they are related to each other.

All the species on Earth look and behave very differently, yet all of them are related. The mold growing on your bread, the trees growing on your street, the insects buzzing about in your room, the pets sleeping by your bed, and you, yourself, are all members of a single type of life that descended from the same source. The evidence for this conclusion is provided by the fact that all living things share the following properties. All life on Earth is made of single cells or groups of cooperating cells. All life on Earth uses the same biochemicals to construct cell parts and to store and use energy. All life on Earth uses the same chemical "language" and chemical structure (DNA) to store and pass on genetic information. Thus, there is a unity underlying all the rich diversity of life on Earth.
