Question 2

Which of the following is a direct consequence of excessive fertilizer use in agriculture on aquatic ecosystems?

Accepted Answer

Eutrophication, leading to decreased oxygen levels and death of aquatic animals.

Question 3

Which air pollutant is primarily responsible for the destruction of the ozone layer, as shown in the air pollutant sources chart?

Accepted Answer

Chlorofluorocarbons (CFCs)

Question 4

What is the main environmental concern associated with the accumulation of plastics in ocean gyres, as depicted in the floating plastics image?

Accepted Answer

Plastics persist for hundreds of years, harming marine organisms and entering the food chain.

Question 5

Which of the following is a sustainable strategy for reducing human impact on the environment, as demonstrated by the green roof at Rockefeller Center?
