To answer one: the acid in acid rain is harmful for the plants and animals who drink it (inhaling acids isn't too fun). It can be very dangerous for those who ingest it. Acid rain also wears down many rocks, ruining classical architecture and some older buildings
Acid rain harms aquatic ecosystems and corrodes buildings. Ozone layer depletion increases UV radiation, causing health issues like skin cancer. The greenhouse effect traps heat but is intensified by human activity, leading to climate change.
