Quizplus · Accepted Answer

Increased processing of salt water to freshwater may have some impacts on the water cycle, but it is the least when compared to the other human activities listed. The other activities all involve changes to the natural water cycle, such as reducing infiltration and evaporation, altering runoff patterns, and increasing water use. Processing salt water to freshwater may affect some oceanic systems, but it does not have a significant impact on the overall water cycle on land.
