Answer:
It was due to colonization
Step-by-step explanation:
The population of America, begins with the invasion and after Christopher Columbus. Because of this, the population fell considerably, between 30 and 90 percent. In 1650 the population of natives was 5 to 9 million inhabitants, who lived in Central and South America.
Due to this colonization process many families and native tribes broke down as a result of the migratory changes to which they had to be subjected and also because of the deaths due to poor living conditions and diseases.
