I didn't buy any food for a year – and I'm healthier than I've ever been theguardian.com

Rob Greenfield gardened, fished and foraged to eat more sustainably and encourage others to do the same. But to succeed, he needed the community
For the last year I grew and foraged 100% of my food. No grocery stores, no restaurants, not even a drink at a bar. Nature was my garden, my pantry, and my pharmacy.

Most people would imagine I live in the countryside on a farm, but actually I live in a city; Orlando, Florida, a few miles from the center. When I arrived here, I didn’t own any land, so in order to grow my food, I met people in the neighborhood and turned their lawns into gardens and shared the bounty of food with them. I’m a big believer in the philosophy “grow food, not lawns”.
