Chapman’s been chronicling dumpster-diving for a few years, but now Frenchman Baptiste Dubanchet is on a quest to bike across Europe, surviving entirely on discarded food. The three-month, 1,900-mile journey from Paris to Warsaw is Dubanchet’s way of raising awareness of food waste in Europe and throughout the world.

While the world’s restaurants and supermarkets combine to throw away an average of 1.3 billion tons of food each year, according to the UN, much of it remains inaccessible thanks to locked dumpsters, health regulations, or business policies.

 For legal reasons, most establishments have a policy against giving away food waste.
