Final answer:
The sentence supports the claim that human activity threatens the vitality of tidal pools, indicating the impact of human actions on marine ecosystems, including shipping, aquaculture, and climate change effects.
Step-by-step explanation:
The sentence that would best support a claim regarding the effects of human activity on marine ecosystems is most closely related to option b) Human activity threatens the vitality of tidal pools. The information provided suggests that human activities such as global commerce, aquaculture, the aquarium trade, shipping, oil and gas extraction, and the emergence of new uses such as wave and wind energy farms have introduced stresses on ocean ecosystems, impacting their health and biodiversity. Moreover, the introduction of non-native species and effects from climate change such as rising sea levels, temperature changes, and ocean acidification are all results of human activities that threaten ocean ecosystems.
Option d) Tidal pools are endangered and need to be protected is somewhat supported because the impacts mentioned do endanger tidal pools. However, the sentence doesn't explicitly state that tidal pools require protection. The other options are not as directly supported by the sentence mentioned since it focuses on human impact rather than the intrinsic complexity or oceanic activity affecting tidal pools.
