For example, instead of buying a bag of chemically produced fertiliser, we can grow nitrogen fixing plants on site, such as Siberian pea tree, gorse or broom. They feed the food plants around them, both from their roots and from being cut and used as mulch around the stems and trunks of the food plants.
People are also biological resources.
With increasing reliance on technology in industrialised cultures, we have more and more unused or underused people, particularly the young and the elderly. These people not only become a drain on an industrialised culture, they may even become destructive to it. They have been disgarded as human rubbish. We can recycle people as well as rubbish by assisting them to contact their dreams and design strategies for fulfilling those dreams to the benefit of the community and the culture.
