Review Questions

• How do megacities influence migration patterns in a country?
  • Megacities significantly influence migration patterns as they attract people from rural areas seeking better job opportunities, education, and living standards. This influx contributes to the rapid urbanization of these areas and can create a cycle where more individuals continue to migrate to cities for perceived advantages. However, this can also lead to challenges such as overcrowding and pressure on local resources.
• What are some common challenges faced by megacities due to their rapid growth?
  • Common challenges faced by megacities include traffic congestion, air and water pollution, inadequate housing leading to slum development, and overwhelmed public services such as healthcare and education. These issues arise from the fast-paced urbanization that characterizes megacities, putting immense pressure on infrastructure and governance systems. Addressing these challenges requires innovative approaches and substantial investment in urban planning.
• Evaluate the impact of megacities on global economics and culture.
  • Megacities play a crucial role in shaping global economics and culture by serving as major centers for finance, trade, and innovation. Their economic activities often contribute significantly to national GDPs while attracting foreign investment. Culturally, megacities become melting pots where diverse populations converge, fostering creativity and cultural exchange. This dynamic not only influences local culture but also shapes global trends in fashion, technology, and social movements.
