The video below is among the best articulated cases for spreading edible gardens. 


From the description on Youtube: "Roger Doiron is founding director of Kitchen Gardeners International, a network of people taking a hands-on approach to re-localizing the global food supply. Doiron is an advocate for new policies, technologies, investments, and fresh thinking about the role of gardens. His successful petition to replant a kitchen garden at the White House attracted broad international recognition.

Key lines
- Food is what our body runs on but it also a form of power. And when we encourage people to grow some of their own food, we we are encouraging them to take power into their hands - power over their diet, power over their health, and power over their pocket book.
- Gardening is a sort of gateway drug for other forms of food freedom. It's not long after we start growing food that we need to learn how to cook it too.
- In order to keep up with the growing population were going to kn more food over the course of the next 50 years than we have in the past 10,000 years combined. We're going to have to grow all this food with less (oil, water, soil, etc). 

Summary
- Gardens are a critical part of the movement to make health and sustainability accessible and viable.
