Paignton Zoo Takes Farming To The Skies (VIDEO)

Many see vertical farming as the natural step in sustaining food production on a large scale, with less resources. Paignton Zoo in Devon, England, is one of the latest to take farming to the skies, using a hydroponic-farming system to grow crops for its animals, Reuters reported. Their farm can grow 11,000 plants, 20 times more than they would using the same space on the ground.

Is this the future of farming?
