Mega cities exemplify the trends of urbanization as they attract large populations seeking economic opportunities and improved living standards. Their rapid growth is driven by both domestic migration from rural areas and international immigration.

In what ways do mega cities face unique challenges compared to smaller urban areas?
Mega cities experience distinct challenges due to their sheer size and population density. Issues like traffic congestion, pollution, and inadequate public services are more pronounced than in smaller cities. The demand for housing often outstrips supply, leading to the proliferation of slums where living conditions are poor.
