Acid deposition can be managed by changing the activity, controlling release, or restoring damage; those levels prevent different parts of the causal chain.
Reduce fossil-fuel use at source, use scrubbers or converters at release, and use healthcare or lake liming for existing damage. Prevention limits new loading; restoration cannot remove upstream emissions.
A scrubber cuts sulfur emissions from a plant, while liming an acidified lake neutralizes stored acidity after deposition.
Restoration such as liming; pair it with source reduction to prevent recurrence.
Restoration is not source control.
