The term ‘biodiversity’ came into use in the late 1980s, and by 1992 international momentum led to the adoption of the Convention on Biological Diversity.
Biodiversity, according to the Natural History Museum, is:
"the term for every living thing on earth from the smallest microscopic organisms to the biggest blue whales and the habitats they depend on.
The rich variety of life is essential for sustaining the natural living systems or ecosystems that provide us with food, fuel, health, wealth and other vital services.
Biodiversity also includes us although we currently pose the greatest threat to nature. We also offer the only hope for protecting and conserving the diversity of life for future generations."
