Question

Chemical pollutants: a. can spread rapidly from the places they are released. b. do not appear to influence global climate change. c. have contributed to global mass extinctions. d. rarely affect natural bodies of water. e. rarely influence animals feeding at higher trophic levels.

Short answer

Based on the careful evaluation of each option, the statement that aligns best with the known impacts of chemical pollutants on the environment is Option A: 'Chemical pollutants can spread rapidly from the places they are released'.

Step-by-step solution

Evaluate Option A

Chemical pollutants can indeed spread rapidly from the places they are released due to factors such as wind, water flow, and absorption by living organisms.

Evaluate Option B

Chemical pollutants do impact global climate change. They can contribute to the greenhouse effect, increasing Earth's temperature, and can also lead to acid rain, which adversely affects wildlife and vegetation.

Evaluate Option C

While chemical pollutants have undoubtedly had devastating effects on many individual species, there's not enough evidence to speak of their contribution to global mass extinctions. Localized extinction events possibly, but global mass extinctions have typically been attributed to other large-scale phenomena like meteor impacts or drastic climate changes.

Evaluate Option D

Natural bodies of water are often heavily affected by chemical pollution. This can lead to issues such as acidification, eutrophication, and harm to aquatic life.

Evaluate Option E

Chemical pollutants can certainly influence animals feeding at higher trophic levels. This is notably seen via biomagnification, where certain chemical pollutants become concentrated in an organism at higher levels of the food chain.
