Causes:
Sulphur and nitrogen oxides are emitted by burning fossil fuels. Such smoke and gases entering the atmosphere make a dilute soup of sulphuric and nitric acids. This falls on the land surface in the form of acid rain damaging the things on Earth.
Impacts:
- Acid rain accelerates the decay of building materials and paints, including buildings, statues, and sculptures which are part of our nation's culture and heritage.
- Acid rain causes respiratory problems in humans, especially for people suffering from asthma. It may cause throat irritation, dry cough, and severe headache.
