Lesson 1: Moderation - take what you need

The first lesson we learn from ancient multi-century civilisations is to take only what we need from nature and waste nothing of what nature provides.  Examples include: native Americans, Eskimos, African Bushmen.  There is no doubt that if everyone aspired to live like native Americans lived, we could all hope to live permanently.  Unless of course we were met with disaster outside of our control.
