What is biodiversity?
the variability among living organisms from all sources, including terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are a part; this includes diversity within species, between species and of ecosystems.
Where do you find the greatest biodiversity?
The richest environments appear to be rainforest and coral reefs but there is considerable debate on how biodiversity is calculated. Species diversity tends to increase towards low altitudes ecosystems which are warm and wet. Tropical Rainforest covers less than 7% of the earth yet has over half of the world’s species.
