Sustainability is expressed as meeting present environmental, social, and economic needs without compromising these factors for future generations A practice cannot be said to be 'sustainable for X years/generations.' The use of any span of time disqualifies the activity. Sustainability is for perpetuity.
Sustainability also means greater efficiency in resource use, ultimately giving benefits to economic growth and overcoming poverty, as well as health and quality of life.
Sustainable design and sustainable development are critical factors to sustainable living. Sustainable design encompasses the development of appropriate technology, which is a staple of sustainable living practices. Sustainable development in turn is the use of these technologies in infrastructure. Sustainable architecture (see Green building) and agriculture are the most common examples of this practice.
Blue ox earthen oven
. The earthen oven at the Blue Ox Millworks in Eureka, California was constructed in 2004 by Appropriate Technology (Engr305
) students at Humboldt State University
. The project took four, three-hour work sessions to complete over a total of four weeks. As of 2007 it is still standing, is in immaculate condition and retains nearly the same heating efficiency as when it was first constructed. This page includes information on the construction of the Blue Ox earthen oven and information and updates on its current condition.
Earthen Ovens have been used for thousands of years by cultures all over the world and they are still built today by people all over. Earthen ovens are made up of just that, EARTH! Sand, clay and straw are used in building these versatile ovens.
An earthen oven can be used to cook the same things cooked in a normal household oven, so long as you can fit it through the door! Often Earthen Ovens are somewhat unique from other ovens in that they don’t have a fire burning continuously to cook with. The oven is heated before any cooking is going to take place. Generally Earthen Ovens are fired for a few hours and the hot coals are then scraped out of the interior. Once the coals are scraped out, the oven is ready to cook in.
