Acceptable existential justification (AEJ)

The period from antiquity to the 18th century, is characterized by very colorful social development, from the development of various civilizations, kingdoms, empires until the formation of States with different social systems and the appropriate personal and social needs and wishes that during this time despite the constant population fluctuations, permanent wars and the spread of deadly diseases, grew by 15%. These additional needs and wishes took influence on the increase of us free goods (forests, minerals, minerals, coal …) for the production of economic goods (food, buildings, boats, clothing, weapons …). But despite all these negative effects on the environment, the major part of the planet was still intact and the existence of mankind with 80% guaranteed.
