If there’s one high school competition I’d love to see, it would be schools competing for which one can do the best job of teaching students how to live more sustainably. Third generation farmer Kaben Smallwood has my vote for creating an aquaponics greenhouse at a rural public school in Kiowa, Oklahoma. Kids are harvesting crops for their school lunches while learning about water-thrifty systems that combine fish and plant farming. His company now has $40,000 and mentoring support to keep growing, with an award from the 2013 Hitachi Foundation Yoshiyama Young Entrepreneurs Program.
