How has the level of pollutants in developed countries changed over time?

Increased greatly
Decreased significantly
Remained constant
Fluctuated without a clear trend

The correct answer is: Decreased significantly

Over time, the advancements in technology and development in infrastructure have allowed developed countries to implement policies and regulations to reduce the amount of pollutants emitted into the environment. This has resulted in a significant decrease in pollutants over time, making option B the most correct choice. Option A is incorrect because while pollutants may have increased in some areas, the overall trend has been a decrease. Option C is also incorrect as there has been a clear decrease in pollutants. Option D is incorrect because there has been a clear trend of decrease, rather than fluctuations.
