Final answer:
The extreme poverty in Brazil's northeast region is caused by rural-to-urban migration, lack of an international port, political instability and corruption.
Step-by-step explanation:
The extreme poverty in Brazil's northeast region can be attributed to several factors:
Rural-to-urban migration: The lack of viable opportunities for families in small farms has led many individuals to migrate to larger cities like Rio de Janeiro and São Paulo in search of employment. This migration pattern has fueled the growth of favelas, which are slums characterized by poverty and inadequate public services.
Lack of international port: The absence of an international port hinders the region's connections to global markets, limiting economic opportunities and development.
Political instability and corruption: The region has been plagued by unstable governments and widespread corruption, which contribute to the wide disparity between social elites and the majority of the population.
These factors, combined with large family sizes and rapid urban growth, have resulted in extreme poverty and unsanitary living conditions in Brazil's northeast region.
