The Man Who Wanted to Change the World: Peter Westerveld, artist and visionary, doesn’t want institutions to resolve the problems linked to earth’s problems. Growing up in Africa, he witnessed the advance of the desert and dedicated himself to finding solutions for the ongoing erosion and desertification of the land. The film follows Peter and the NGO working with him to realise his project; to build contour trenches that capture and store rain water under the surface and replenish the desert land.
