SOIL: Rewilding the Underground
By Freya Mulvey
SOIL: Rewilding the Underground is an independent six-part documentary told by the farmers, First Nations custodians, scientists and communities who are turning dirt degraded back into living soil and safeguarding our planetary future. It is a journey into the upper layer of the Earth, the source of our food, home to the most biodiverse ecosystem on our planet, and a crucial part of the carbon cycle that regulates our climate, and the temperature of Earth’s atmosphere.
