  1. Increased respiratory illnesses

  2. Cardiovascular problems

  3. Cancer

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

Poor air quality in urban areas can have severe health implications. Exposure to air pollutants can increase the risk of respiratory illnesses, cardiovascular problems, and even cancer. These health effects can significantly impact the well-being of urban residents.

Multiple choice

Which of the following is a potential consequence of poor air quality on urban ecosystems?

  1. Damage to vegetation and reduced biodiversity

  2. Increased susceptibility of plants to pests and diseases

  3. Alteration of soil chemistry and nutrient cycling

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

Poor air quality in urban areas can have detrimental effects on urban ecosystems. It can damage vegetation, leading to reduced biodiversity. Air pollution can also increase the susceptibility of plants to pests and diseases.
