This is a culture passed down for many generations

South American tribes were formed to serve their subsistence needs before the advent of researchers and information collectors. These tribes have existed for many centuries, so they are also less affected by the changes in human civilized life. They still live instinctively, close to nature, even though the life around them has changed. They do not have to worry about the economic and social risks of poverty. Life revolved around earning food, hunting and gathering and maintaining a life in the tribe.

Many South American tribes far from civilized life have survived because these tribes exist on distant lands, surrounded by ethnic, linguistic, and cultural barriers. This is also a cause that helps them maintain their distinction from the outside world. Furthermore, many South American tribes were also respected and enjoyed legal rights enacted by central national governments. Thus, these tribes can continue to undo and maintain their old cultural product without being undermined by conflict. Due to the independence of many South American tribes, many of these peoples have chosen to live a pure lifestyle, not participating in civilized life.

Many peoples also have a historical power to keep the old way of life and prevent any outside influence from entering their lives. People also believe that simple life is a kind of religion as well as the best way to live for them. Contactless tribes have developed completely self-sufficient and extremely diverse ways of life. They add a lot to the richness of human life.
