Six years ago, Tony Hillery was volunteering at a New York City public school in Harlem. In the lunchroom one day, he met a kindergartner who told him that tomatoes grew in the supermarket. It was a real conversation, and she was adamant," he recalled. "And then I did an informal poll with the other students, and they agreed. They had no idea what is healthy food or where it comes from." Many students lived at or below the poverty line, he said, and lacked affordable, fresh food. But Hillery was shocked to find that many children couldn't properly identify vegetables. Across the street from the school was an abandoned community garden, and Hillery had an idea. He made a few calls, registered it with the city and turned it into what has become a thriving urban farm. "I got this big patch of dirt in the middle of Harlem, and I had never planted anything prior to then," he said. Today, his nonprofit, Harlem Grown, has 10 urban farms throughout the neighborhood. Hillery and his staff teach children how to grow food from seed to harvest and cook healthy meals using the fruits of their labor. Yet Hillery insists that urban farming is the hook to engage the youth. Then his group further enriches their lives through mentoring and exposure to higher education and possible career paths. "The whole world can come through this little farm," said Hillery, whose programs reach more than 4,000 young people a year. "Poverty is just lack of access. We bring that access and that opportunity here to them."
