The Amazonian indigenous peoples are traditionally semi-nomadic native
tribes subsisting by hunting, fishing, gathering of wild plants, and
horticulture. Many of the original native tribes that existed in 1492
when Columbus first reached the Americas have died out or have become
assimilated as a result of European immigration and settlement Some
estimate that the population of native tribes in pre-Columbian times was as
high as six million people. At present, only a relatively few native
tribes still survive with their original cultures intact in isolated areas
of the Amazon jungle, principally along the border of Peru and Brazil.
