Phosphorous: Geology, Life and us.
Phosphorus, an essential component of all known living organisms, is derived
Many of the key events in earth history, can be linked to significant changes in the
natural utilisation of phosphorus. Examples include major steps in evolution,
including the origin of life itself and the origin of bony skeletons, like ours.

eutrophication and environmental destruction.
Find out how we are all, intimately, part of the geological phosphorous cycle!
