Ahead of World Environment Day, UNEP Showcases Methods such as Condensing Cows, Storing Seabirds in Sealskins and Freeze-Drying Potatoes in the Open Air.

From condensing the meat of whole cow to the size of a human fist, to preserving seabirds in sealskins, there are hundreds of ways in which traditional cultures can teach the wasteful developed world how to preserve and conserve one of our most-precious yet most-squandered resources: food.

Each year, an estimated one third of all food produced—an astonishing 1.3 billion tonnes, worth around US$1 trillion—ends up rotting in the bins of consumers and retailers or spoiling due to poor transportation and harvesting practices.
