Transcript of Biosphere and biodiversity
Where is this animal from and why is it unusual?
Lithosphere = the hard, outer surface of the earth
Biosphere = All of the living things (flora and fauna) on the earth.
Atmosphere = Gaseous environment adjacent to the lithosphere
Geosphere = Lithosphere + atmosphere + biosphere

It is only now that we are beginning to realise the potential medicines and crops that we can obtain from a wide range of different organisms. Only by maintaining biodiversity can we be sure that these benefits will be available for future generations.
Biodiversity means having as wide a range of different species as possible. Maintaining biodiversity is an important part of using the environment in a sustainable way. Indiscriminate use of the environment, for example cutting down large areas of the rain forest to grow crops such as soya, results in a large number of species becoming extinct and reduces biodiversity.
