God has gifted many things to us and we only have t preserve these precious gifts as these are major and most vital things for all living beings on the earth for their survival. So, the well-being and survival of human being depend on millions of species of plants and microbes which include species and varieties of crop, livestock and wildlife. Biodiversity, which refer to the variety and variability among living organisms in our environment and the ecosystems complexes in which they occur is facing ecological catastrophes and within the next few decades it is likely to extinct according to the report "People and the Environment", released recently by the US based WRI. Rapid loss of Biodiversity is caused by the destruction of Habitats of wild animals by man, hunting overexploitation, using pesticides, pollution of water, air, noise etc. Serval techniques, legal aspects and action plans have been implemented for the conversation on Biodiversity. Biotechnology has also added many scientific and engineering principles for conservation of Biodiversity and its impact has also been discussed. Biodiversity maintains ecological balance and evolutionary processes and it has become an important topic for its conservation and management. This book is a sincere effort of the authors not only for spreading awareness but also for providing information about the variety of living things existing in the environment and it suggests ways for its conservation and development.

Forests play important role in combating desertification preventing erosion problems other protective functions climatic change and acting as carbon reservoirs and sinks. Forests the biodiversity they contain and the ecological function they maintain are a heritage of mankind. The vital role of forests in protecting fragile ecosystems watersheds and freshwater reservoirs and as store houses of rich biodiversity should be recognized. Forests contain not only woody species and wild animals but also a wealth of other species of actual or potentially socio economic importance at the global national and local levels including wild relatives of important crop species. Biodiversity is the variety and variability of plant animal and micro organism in a ecosystem. Biodiversity in wild and domesticated forms is the source for most of humanity food medicine clothing and housing most of the cultural diversity and most of the intellectual and spiritual inspirations. In other words it is the very basis of man's being. Currently there is severe and widespread loss of biodiversity because of a variety of factors and therefore its conservation is of utmost importance. Conservation and development are partners in the process of environmental protection. To maintain and increase the ecological biological climatic socio cultural and economic contributions of forests their conservation and management are urgently required. Biological diversity (biodiversity) is also to be preserved to achieve sustainable development. The book is a sincere effort of the authors to provide compiled information on the subject matter of forest environment and diversity. It includes the impact of forests on environment basic concept status and extent of biodiversity its loss and suggests ways and means of conservation for achieving sustainable development. 556 pp.
