Youth in Wake County were selected for the 4-H Revolution of Responsibility, a national campaign which highlights youth who are making a measurable difference right where they live. Using mapping technology, Wake County 4-H youth identified community ‘food deserts’ – areas lacking in access to healthy foods. They also teamed up with Advocates for Health in Action (AHA) to persuade store owners to improve food selections in the community by adding healthier choices. The 4-H youth mapping project was funded initially through a grant from the John Rex Endowment and continues to receive funding and support from AHA as well as Wake County Human Services.
