Sum of different species of animals, plants, fungi and microbial organisms living on Earth and the variety of habitats in which they live.
Increases productivity and stable ecosystem
What would happen if there are many many lions?
Higher biodiversity ecosystem are more productive
Paul Ehlrich: Rivet Popper Hypothesis – (aeroplane as ecosystem and rivets as species) – If rivets are removed if will not affect safety in beginning but later will become weak and if wings (major species) removed there would be immediate threat
50 million species of plants and animals exist
1.4 million species have been identified so far
Term given by Walter Rosen in 1985
Term popularized by Edward Wilson in 1992
Species rich regions – Tropics and Coral reefs
Of total species, 70% species are animals (amongst animals highest proportion is insects) while 22% are plants
Around 15,000 new species are discovered every year (thanks to Species 2000 & Global Biodiversity Information Facility)
