Explanation:

Acid rain is a cause of water pollution. Preventing acid rain would help prevent a cause of water pollution. Absorbing methane - gas odors is not related to water - pollution causes. Increasing oxygen levels in polluted water is treating polluted water, not preventing a cause. Keeping people and animals from drinking contaminated water is about limiting effects, not preventing a cause.
