Biodiversity or biological diversity is defined as:

The variety of all living things, including plants, animals and micro-organisms, the genes they contain, and the ecosystems of which they form a part. It is not static, but is constantly changing.  It is increased by genetic change and evolutionary processes and reduced by processes such as habitat degradation, population decline, and extinction.
