The spiritual atmosphere can be pure and impure, life nourishing or stifling. The physical atmosphere can also be pure or polluted, life nourishing or stifling. In this context pure air means the abundance of man’s physical living conditions, the pureness and the absence of harm in the whole ecological system, ensuring man’s living space. It also means the balance, which has to exist between the food- and energy resources of our planet for the daily needs of its 7 billion inhabitants.
