NOT QUITE CROP CIRCLES!

In Israel, Moti Cohen is pioneering a new spin on an very old method first used in Asia. The idea is to create a circular farm that provides people with fish and plants to eat in a closed loop. The crops feed off the waste created by the fish, while the fish thrive on the oxygen made by the crops. Both become an important source of nutrients for the people –– with no waste, fertilizer or much water needed. “It is an ancient method that we can bring up to speed now that we have electricity, fish ponds and great technologies to make aquaponics better than it ever has been,” he says.
