The way I try to understand the problem, is not by applying some given social norm or idea to these problems. Since these may not be scientific. A product of culture or religion or politics. But to understand the human animal and to understand what environment it lived in. And to compare that natural habitat, to the artificial habitat of modern society. To see what problems exist with modern habitats.
A friend of mine likes to watch a programme on TV, about Chimpanzees in a Zoo. The Zookeeper have intimate knowledge about the physical and social needs of these animals. And provide a perfect environment for them. In many respects, these animals have much better quality of life than many humans. They thrive.
But human animals are not treated in the same way as these captive Chimps. Human captive Chimps are given unnatural environments to live in. In this human Zoo. They get separated from parents and go to school. They eat food not meant for them. They live in enclousers in close proximity, called towns. They are encouraged to smoke and drink alcohol. They are subject to tiresome work and stress. They do not thrive.
So question is simply how to change human environment, to be a healthy one. If we can do it for a Chimp in a Zoo. Then why can we not do it for a human animal? How are human animals to live? What is their ideal environment?
