Life and Spirituality

O xygen in the atmosphere comes mainly from photosynthesis in excess of decay of the products of photosynthesis. The precise proportions of oxygen and carbon dioxide in the atmosphere depend on several environmental and cosmic factors. It has varied with time on earth and must be different on different planets  in the universe bearing liquid surface water and an atmosphere. What precise combination is best for oxygen and carbon breathing life in general and human life in particular is a matter for debate and study. We presently manage with around 21 percent oxygen, the rest being mainly nitrogen. Carbon dioxide in the present day atmosphere even after much use of fossil fuels is around .04% only. W ith modern technology it is a fairly simple matter to produce controlled atmospheric mixes different from the normal atmosphere in small enclosed spaces such as bars, meditation rooms and restaurants. The setting up of such spaces for use over limited periods may be of great

A s mankind burns fossil fuels to meet its energy needs, carbon emissions are added to the atmosphere. Some of them such as particulate matter are short lived but others such as carbon dioxide is a long lived component. A previous note explored the impact of carbon dioxide emissions on climate change: (http://someitemshave.blogspot.in/2014/04/a-new-perspective-on-climate-change.html )  It was concluded that a much higher level of around 1000 ppm of carbon dioxide appears to be beneficial for the green side of life – plants and trees – because carbon dioxide is to plants as oxygen is to animals. It was also stated that the full impact of such increases on global ecology is a matter for further study.   The present note touches upon a topic that has received little attention so far – The impact of increased carbon dioxide on human physical and spiritual evolution. It is assumed that both go hand in hand as regards humans. The present brief note merely makes initial comments with
