His class attendance went from 40% to 93%. Because of a garden?

During his work, Stephen discovered that most of the kids who are considered learning disabled wouldn't have been if they'd had proper prenatal nutrition.

Then fate set him and his students on a new path. One day, someone sent him a donation of daffodil bulbs.

Finding that the bulbs had turned into flowers behind the radiator inspired them to dream big.
So he and the kids created the Green Bronx Machine. The Green Bronx Machine is a nonprofit devoted to growing healthy food curriculums and economies locally. It teaches kids how to be healthy and provides them with healthy food options, which in turn helps them focus and perform better in and out of school.

Together, they've created a school curriculum around healthy eating and gardening. The students grow food (30,000 pounds of it to date), and they create sustainable gardens on roofs and in classrooms all over New York (creating jobs for some of the teens in the program). The kids have significantly increased their academic achievement.

And even better? The students get to eat the things they grow and bring food home, too, while learning how to farm and manage food production at the same time.
