INTRODUCTION

The term Biodiversity was first coined by Walter G. Ro

1986.The biosphere comprises of a complex collections of in

organisms, known as the Biodiversity, which convital life support for survival of human race.

Biological diversity, abbreviated as biodiversity, repsum total of various life forms such as unicellu

protozoa, bacteria, and multi cellular organisms suchfishes, and mammals at various biological levels genes, habitats, and ecosystem .

CONCEPT OF BIODIVERSITY

Biodiversity is the variety of life forms on earth and thinterdependence of all living things.

As defined in United Nation Earth Summit signed at Rio(Brazil) in 1992 by 154 countries, Biodiversity is theamong living organisms from all sources includingterrestrial, marine and other aquatic eco-systems and thecomplexes of which they are part : this include diversity

between species and ecosystem.

India is one of the twelve-mega biodiversity countries oand one of the four in Asia.

RECENT ISSUES ON BIODIVERSITY

Some 75 per cent of the genetic diversity of crop

plants have been lost in the past century.

Some scientists estimate that as many as 3 species per hour extinct and 20,000 extinctions occur each year.

Roughly one-third of the worlds coral reef systems have beor highly degraded.

About 24 per cent of mammals and 12 per cent of bird speccurrently considered to be globally threatened.

More than 50 per cent of the worlds wetlands have been drpopulations of inland water and wetland species have declincent between 1970 and 1999.

CONCLUSION

Biodiversity is our life. If the Biodiversity gets lost at

in near future, the survival of human being will be th

it is our moral duty to conserve Biodiversity Environment. Long-term maintenance of specie

management requires co-operative efforts across entir

Biodiversity should be dealt with at scale of

ecosystems rather than at species level.
