But it is a good thing if we can understand the places where we can live, so that we can choose the place that suits us best and makes us feel the most comfortable in our lives.If everyone is self-sufficient and self-sufficient, the knowledge that people need is nothing more than how much land they need to support their own lives.A primitive man does not need anyone, and he will never envy others. He does not understand, and he will not want to understand any place other than his own.If he needs more land in order to survive, he will also avoid inhabited places, and he can directly fight wild animals and eat them for a living.
