Aside from the obvious benefits of improving the culture surrounding food, especially in poor neighborhoods, what Ritz has managed to accomplish with his garden walls is to share the idea with other schools in the Bronx neighborhood and other regions. The project is called the Green Bronx Machine, and the idea has reached other parts of the country.
