Question 9 • Grade 8 World Cultures and Geography A
Answer:
Humans alter the environment to grow crops and raise livestock, which provides food for communities. We build homes and towns to provide shelter and places to work. Roads, bridges, and ports make it easier to travel and transport goods. Dams and reservoirs can store water, help control floods, and generate electricity. We also develop land and natural resources to create jobs and produce materials people use every day. These changes can improve living standards, although they may also have environmental costs.
