As the world's population grows and farming space is at a premium, we are quickly running out of land to grow enough crops to feed everyone.
For years, we've been told that the future of farming was vertical, growing crops indoors in more space-efficient buildings. But this revolution has not yet come to pass, with currently only 30 hectares of vertical farming space worldwide. An increase in energy costs around the world has led to several nascent projects being scrapped.
But now a new agricultural company called Plenty, based in San Fransico, believes it has the answer. Using new unique 3D architecture that grows crops up to two stories high in huge towers, they believe that they can revolutionise farming.
Plenty believes they can grow 350 times more yield from the same amount of land as conventional farming, and they can do it almost anywhere in the world. Their aim is to grow up to two million kilograms of leafy greens annually.
Join us as we take a look around their state-of-the-art facilities, and see how farming might look in the future.
