SOIL, HUMUS, EARTH

The soil is a living ecosystem that covers the earth from which we obtain 95% of our food: a very thin layer (70-200 cm, if compared to the earth's surface) which, like a skin, protects the planet from sudden changes in temperature, atmospheric variations, sequesters carbon more than forests, contains enormous biodiversity, retains water, processes vital energy... It is actually 30 cm that makes the Planetary Garden possible from which we all feed ourselves and in particular the first fertile 5-10 cm of humus. Soil is a NON-renewable resource that we are consuming at incredible rates.
