Learn all about Humus, 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.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
