Biodiversity means the diversity of life forms. It is a word commonly used to refer to the variety of life forms found in a particular region. Diverse life forms share the environment, and are affected by each other too. As a result a stable community of different species comes into evcistence. Humans have prayed their own part in recent times in changing the balance of such communities is affected by particular characteristics of land, water, and climate and so on. Rough estimates state that there are about ten million species on the planet, although we actually know only one or two millions of them. The worm and humid tropical regions of the earth, between the topic of concern and the topic of Capricorn, are rich the diversity of plant and animal life. This is called the region of mega diversity, of the biodiversity, of the planet more than half is concentrated in a few countries- brazil, Colombia, Ecuador, Peru, Marico, Zaire, Madagascar, Australia, China, India, Indonesia and Malaysia.
