Multiple choice

How does climate change affect the health of urban residents?

  1. It increases the risk of heat-related illnesses

  2. It increases the risk of respiratory illnesses

  3. It increases the risk of waterborne illnesses

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Climate change is expected to have a negative impact on the health of urban residents by increasing the risk of heat-related illnesses, respiratory illnesses, and waterborne illnesses. This is due to the fact that climate change is causing the Earth's atmosphere to warm, which in turn leads to changes in weather patterns that favor the spread of disease.
