Biodiversity (Biological diversity) is the diversity of life at three levels,
i.e. variability in genes (within species), diversity of different taxa among living
organisms (different plants, animals and microorganisms) present on earth, and
the variety of ecosystems (terrestrial, marine and other aquatic ecosystems) in
which they are part (UN 1992). In practical sense, biodiversity is expressed as
part of the ‘quality of life’ and includes all of its manifestations
