Humus: The Essential Ingredient. Graeme Sait at TEDxNoosa

Humus is undoubtedly the fat of the land. The layer of soil essential for healthy food production which is being gradually depleted by unsustainable farming practices. Graeme Sait a lifelong human and soil health educator explains how 467 billion tonnes of carbon has been released from the soil into the atmosphere, and that we urgently need to return that carbon to the soil, and start replenishing the humus in order to reverse the impact.
