About 795 million people, or one in nine, do not have enough to eat. According to The Hunger Project, 9 percent of the world's under-nourished people live in developing countries. A Nashville non-profit is trying to shrink that number by teaching others how to grow.
Carl Burkybile is on a life-saving mission.
"What we're doing here is the difference between death and survival," he said.
Burkybile is the Director of Agriculture for Healing Hands International, a non-profit that teaches sustainable farming to those who need it most.
"So when we're in Africa we say to people, 'Don't think about what you don't have. Think about what you do have. Use what you have.' They have no money to buy a wooden box, they have no money to buy fertilizer. So we use what they have," he said.
The training starts at demonstration gardens in Nashville.
"American style. African style or developing-country style," he explained. "These beds down here are very heavily sand so we're looking at things that would grow well in sandy soil. We have squash and zucchini, cantaloupe and watermelon."
From Nashville, trainers take what they learn and help educate people in Africa, South America and beyond.
"Typically we would do about 100 workshops in a year and train about 5,000 people."
