How could we strengthen social support for food gardening?

Widespread hunger in the world is due mainly to the fact that people don’t care enough about one another’s well-being. Caring can be increased by encouraging social interaction. This can be done in many different ways, but the core idea here is to help people produce food for themselves. Many people who produce food in their own gardens gladly share it with their neighbors. They also share their knowledge and enthusiasm for gardening. This is a huge underutilized resource. The project proposed here is intended to facilitate that sharing.
