The Biodiversity or biological diversity is a term coined to describe the immense variety and richness of life on this planet. Biodiversity includes not only the many species that exist, but also the diversity of populations that make up a species, the genetic diversity among individual life forms, and the many different habitats and ecosystems around the globe. The use of the term biodiversity grew out of a concern that efforts were needed to conserve, not just particularly charismatic animals, but the diversity of life around the world, including many plants and animals that will never grace a letterhead or be the focus of an international campaign. There are many ongoing efforts local, national, and international to balance the needs of human populations with the protection of endangered and threatened species. Nature has varied forms of creation. If all these survive, living would be smooth for all species on earth. Thus, bio-diversity would mean that there is need for diverse biological varieties to coexist without the threat of extinction. Thus biodiversity would simply mean varieties of species right to existence. It also would mean that no one has the right to threaten a species' right to existence. Man, being the homosapien should restrain from actions that would erode species but do everything to protect them from extinction. This will not only protect the environment but also enable smooth human survival as well. Thus, all species are equally important for the sustenance of all human and sub-human species. Hence, there is an urgent need to strengthen the food chain of all living creatures with sustainable and judicious use Biodiversity or biological diversity is the richness in species of all living micro and macro- organism's occurring in a given habitat.The word was coined in 1985 and during the 1990s has become very widely used in the scientific circles. According to the World Resources Institute, Biodiversity is the variety of the world organisms, including their genetic diversity and the assemblage they form. It is the blanket term for natural biological wealth that undergirds human life and wellbeing. The breadth of the concept reflects the inter-relatedness of genes, species and ecosystems, because genes are the components of species and species are the components of ecosystems. Therefore, altering the make-up of any level of this hierarchy can change the others; species are central to the concept of biodiversity. Forests play a major role in conserving biodiversity. Climate of a place and the species inhabited by it are regulated by the forests. An increase of the amount of Carbon Monoxide is the most common consequence of forest depletion resulting both from cutting and burning of trees. It is this carbon dioxide which reaches the upper later of atmosphere and gives rise to the greenhouse effect resulting in global warming. Flooding and erosion of soil also result from deforestation as roots of trees assist in keeping the soil from being washed away. Other indirect effects include the melting of snow and ice cover over the Polar Regions and as a result sea levels have risen by as much as 100-200mm in last 100 years. The disturbed weather conditions like drought, floods, acid rain, hurricanes causing havoc to human race as well as plants and animals species on the earth clearly indicate imbalance in ecological systems. Since climatic changes also affect the life forms that sustain, many species are under the threat of being lost with climatic changes taking a drastic shape. It is important to control the economic activities that are highly inefficient and are
