Answer: growth of shantytowns.
Step-by-step explanation:
A shanty town is a settlement of improvised construction created out of plywood, corrugated metal, plastic, cardboard, and other materials. Shantytowns usually lack proper infrastructure, sanitation, electricity, and many vital necessities.
The rising urbanization of poverty in developing nations, especially in Latin America, has boosted the creation of shantytowns.
