Final answer:
Buffer zones can help regulate the acidity of aquatic environments and prevent pollutants from altering the pH balance.
Step-by-step explanation:
Buffer zones can help regulate the acidity of aquatic environments. They act as a barrier between human activities and natural resources, helping to prevent pollutants from entering the water and altering the pH balance. For example, buffer zones around agricultural fields can absorb excess nutrients and prevent runoff into nearby streams or rivers, which can result in eutrophication and acidification of the water.
