The soil beneath our feet is the basis for our food supply, an indispensable reservoir for greenhouse gases. And it is in danger, because "dirt is not sexy". That's how celebrity chef and environmental activist Sarah Wiener sums it up. We use our soils as if they were inexhaustible.

But to form ten centimeters of fertile soil, our planet needs more than 2,000 years. As a result, our food source is at risk - from us humans! What does this mean for the future? How must agriculture and society change so that we can pass on a living world with living soils to our children?
