The Blacks' backyard mini-farm includes three large raised beds built from 4-by-4-inch redwood posts stacked five high to create deep, sturdy and handsome planting areas.
The biointensive method provides many benefits as compared with conventional farming and gardening methods, and is an inexpensive, easily implemented sustainable production method that can be used by people who lack the resources (or desire) to implement commercial chemical and fossil-fuel-based forms of agriculture.
At a sufficient angle, solar cells are cleaned by run-off rain water and therefore have almost no life-style impact. Many areas have long winter nights or dark cloudy days. In these climates, a solar installation might not pay for itself or large battery storage systems are necessary to achieve electric self-sufficiency. [14]
A recent concept design by Eric Wichman shows a multi-family community, which combines all of these technologies into one self-sufficient neighborhood. To grow the community you simply add neighborhoods using the same model as the first. A self-sustained community reduces its impact on the environment by controlling its waste and carbon footprint.
Self-sustainability is a type of sustainable living in which nothing is consumed other than what is produced by the self-sufficient individuals. Examples of attempts at self-sufficiency in North America include simple living, food storage, homesteading, off-the-grid, survivalism, DIY ethic, and the back-to-the-land movement.
DIY has been described as a "self-made-culture"; one of designing, creating, customizing and repairing items or things without any special training. DIY has grown to become a social concept with people sharing ideas, designs, techniques, methods and finished projects with one another either online or in person.
Plant domestication is seen as the birth of agriculture. However, it is arguably proceeded by a very long history of gardening wild plants. While the 12,000 year-old date is the commonly accepted timeline describing plant domestication, there is now evidence from the Ohalo II hunter-gatherer site showing earlier signs of disturbing the soil and cultivation of pre-domesticated crop species.

The Buy Nothing Project encourages local communities to focus on improving the community in which they live [7] and keep groups small and local to minimise distance travelled to pick up items. [8] There is no overt criticism of consumerism , but the project's goals include saving money and reducing waste. [ 9 ]
