Modern civilisation separates the human body from nature with negative consequences.
It is astonishing to read that up to 90% of South Asians leave school with myopia (shortsightedness). Why? Because their modern education system keep the children away from natural light. Natural light causes the eyes of children to readjust to normality, which because of the lack of it means all the children in South Asia will remain myopic, and a large number will go blind.
Rickets, the bone disease of 200 years ago in Britain, has made a return in the modern era. Rickets is due to lack of vitamin D. The skin can manufacture vitamin D in sunlight, and it can be obtained through diet. British children eat a poor diet, and now spend much of their time indoors, hence they are away from the sun. Stranger danger, television, video gaming, scrapping of breaks in schools, limited play areas all drive children indoors away from the sun. When children are in the sun, they are covered in sun blocking cream, which blocks or reduces the vitamin D producing effects of the sun on the child’s skin.
Studies are showing that the obsession with cleaning means children are denied the opportunity to play in the dirt, which impacts the development of their immune systems.
Nature is needed by children to develop. Our bodies are designed to live and survive in nature. Modern civilisation has created living conditions which separate human beings from nature, and often runs against the needs of our own bodies to be a part of nature.
