Guerilla Gardeners

With the paving over of American, sale of public lands to resource extrating companies, and the ownership of much of the commercial garden products by one or two chemical companies (that of course have a vested interest in plants that require chemical fertilizers and insecticides to survive) --- some people are fighting back. They are adding food production to the land in unlikely pieces of land, mostly public spaces that are underused.
Take a look at the guerilla gardening site called "Primal Seeds."

An urban adventure at the threshold of nature and culture, taking back our own time and space, transforming the urban desert, into a provider of food and a space where people meet face to face to discuss and participate directly in the remaking of their own towns and cities.
