Biodiversity refers to the variety of life. The UN Convention on Biological Diversity provides the following definition: 'Biological diversity' means the variability among living organisms from all sources including, interalia, 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.î

Biodiversity is vital for humans because so much of what we require comes from nature such as fuel, food, medicines. There are estimated to be 8.7 million species (give or take 1.3 million and excluding bacteria) on Earth (source: UNEP).
