ˈbaɪ.əʊ.sfɪər/ noun

We can survive as a species only if we live by the rules of the biosphere. Biodiversity is one of those rules.

Our biodiversity provides the life supporting systems that enable all organisms, including humans, to survive. Our wetlands purify water and help prevent flooding and drought. Indigenous forests provide carbon sinks and purify the air we breathe as well as providing recreation and amenity values.

Biodiversity is essential for the processes that support all life on Earth, including humans. Without a wide range of animals, plants and microorganisms, we cannot have the healthy ecosystems that we rely on to provide us with the air we breathe and the food we eat. And people also value nature of itself.

There are lots of ways that humans depend upon biodiversity. It is vital for us to conserve it. Pollinators such as birds, bees and other insects are estimated to be responsible for a third of the world’s crop production. Without pollinators we would not have apples, cherries, blueberries, almonds and many other foods we eat. Agriculture also relies on invertebrates – they help to maintain the health of the soil crops grow in. Soil is teeming with microbes that are vital for liberating nutrients that plants need to grow, which are then also passed to us when we eat them. Life from the oceans provides the main source of animal protein for many people.
