  • Habitat destruction happens
• What is the significance of the book mentioned in the study material?

  • It is a renewable resource
  • It keeps providing information
  • It is a gift that keeps giving
• Why can't we just use every resource available?

  We must consider the impact of our actions
• What should you think about when starting a major mining project?

  The impact of your actions
• What is the difference between finite and renewable resources?

  Finite resources cannot be replenished quickly
• What are the key differences between finite and renewable resources?
