World's Daily Food Production
About 17 billion kg of food produced every day to feed 8 billion people/Collective & Conceptual
Humanity produces roughly 6 billion tonnes of food per year, which works out to about 17 billion kg per day. This includes grains, fruits, vegetables, meat, dairy, and seafood from farms, ranches, and fisheries across every continent except Antarctica. Roughly one third of all food produced is lost or wasted before anyone eats it, which amounts to about 1.3 billion tonnes per year thrown away while 800 million people go hungry.
