Sometimes there are simple solutions to universal needs that don’t require coal fired electricity, fossil fuels, or even solar panels or wind turbines. Around a third of the world’s population have no access to electricity. If you’re like me, you’ve spent your entire life being able to plug in. Do we ever give a thought to what life would be like if the various appliances we’ve come to rely on were to suddenly stop working?
One of the most energy guzzling appliances in our carbon footprint portfolio is the refrigerator. One modern day genius, mindful of this basic need to preserve food, has solved the problem for many. From a family of pot-makers, Mohammed has made ingeniously simple use of the laws of thermodynamics to create the pot-in-pot refrigerator, called a Zeer in Arabic. Here’s how it works.
You take two earthen pots, both being the same shape but different sizes, and put one within the other. Permaculture Pros site. YouTube channel. Sustainability Store. Free range. Commercial free range hens A small flock of mixed free-range chickens being fed outdoors. Free range denotes a method of farming husbandry where the animals, for at least part of the day, can roam freely outdoors, rather than being confined in an enclosure for 24-hours each day.[1] On many farms, the outdoors ranging area is fenced, thereby technically making this an enclosure, however, free range systems usually offer the opportunity for extensive locomotion and sunlight prevented by indoor housing systems.
Free range may apply to meat, eggs or dairy farming. The term is used in two senses that do not overlap completely: as a farmer-centric description of husbandry methods, and as a consumer-centric description of them. In ranching, free-range livestock are permitted to roam without being fenced in, as opposed to fenced-in pastures.

Permaculture. With its system of applied education, research and citizen- led design permaculture has grown a popular web of global networks and developed into a global social movement[citation needed]. The term permaculture was developed and coined by David Holmgren, then a graduate student at the Tasmanian College of Advanced Education's Department of Environmental Design, and Bill Mollison, senior lecturer in Environmental Psychology at University of Tasmania, in 1978. [1] The word permaculture originally referred to "permanent agriculture",[3] but was expanded to stand also for "permanent culture", as it was understood that social aspects were integral to a truly sustainable system as inspired by Masanobu Fukuoka’s natural farming philosophy.
It has many branches that include, but are not limited to, ecological design, ecological engineering, regenerative design, environmental design, and construction. History[edit] Several individuals revolutionized the branch of permaculture. In Australian P.A.
