Growing upward: future farms in NC could be vertical

By Luke Shealy

The UN estimates that by 2050, there could be nearly ten billion people on earth, putting a strain on the food supply. But the solution to feeding the world may be growing upwards instead of outwards. The U.S. Department of Agriculture is investing in vertical farming in the hope that it will increase production. At N.C. State University, students and faculty are experimenting with new technology and studying how this could affect North Carolina’s agricultural future.
