How does air pollution contribute to environmental damage, resulting in economic costs?
-
It damages forests and ecosystems, affecting biodiversity and ecosystem services.
-
It enhances soil fertility, boosting agricultural productivity.
-
It purifies water bodies, reducing water treatment costs.
-
It promotes cloud formation, increasing rainfall and benefiting agriculture.
A
Correct answer
Explanation
Air pollution can cause damage to forests and ecosystems, leading to a loss of biodiversity and ecosystem services, such as carbon sequestration and water purification, which have economic implications.
Which of the following is NOT a potential economic benefit of reducing air pollution in mountainous areas?
-
Reduced healthcare costs
-
Increased tourism revenue
-
Enhanced agricultural productivity
-
Accelerated deforestation
D
Correct answer
Explanation

-
Loss of biodiversity
-
Soil erosion
-
Climate change
-
All of the above
D
Correct answer
Explanation
