The past is the key to the present and the future.

Foulden Maar was created 23-million-years-ago when a volcano erupted to form a shallow crater that filled with water. Over time, the bottom of the lake was built up with layers of microscopic algae to create a diatomite deposit. This deposit also contains a wealth of fossils and historic climate data, spanning hundreds of thousands of years.

But this unique geological treasure is at risk. Plaman Resources Limited plan to mine the entirety of Foulden Maar, including the fossils and climate data it contains. They will export the diatomite as a stock food supplement on factory farms and feedlots, and as a fertiliser on environmentally destructive palm plantations in south-east Asia.
