Questions & Answers

Q: What is urbanization and why is it important?

Urbanization is the creation and growth of cities with higher population densities. It is important because it plays a significant role in shaping economies, societies, and the environment, with more than 50% of the world's population currently living in cities.

Q: What are the advantages of high population density in cities?

High population density allows for easier coordination of community efforts, such as recycling and public education. It also provides better access to services like medical care and family planning for urban residents.

Q: How does the high population density in cities impact the environment?

The high population density in cities can strain natural resources and lead to increased air and water pollution. The concentration of people in one space can generate more pollution and cause challenges in waste management and resource depletion.

Q: How can sustainable planning address the negative environmental impacts of cities?

Sustainable planning involves increasing green spaces in cities, such as through green roofs and rain gardens, which help prevent runoff and filter pollutants. It also includes measures like permeable surfaces and clean forms of energy to reduce pollution and resource consumption.

Summary & Key Takeaways

  • Urbanization is the creation and growth of cities, which currently house over 50% of the world's population, leading to advantages such as easier coordination of community efforts and better access to services.

  • However, high population density in cities can have negative environmental effects, causing strain on natural resources and generating air and water pollution.

  • Sustainable planning can mitigate these effects by increasing green spaces, such as green roofs and rain gardens, and reducing pollution through measures like permeable surfaces and clean forms of energy.
