* Air pollution: SO2 is a major component of smog, which is a type of air pollution that can cause respiratory problems, such as asthma and bronchitis. SO2 can also damage plants and animals, and can contribute to the formation of acid rain.
* Acid rain: Acid rain is caused when SO2 and other pollutants in the atmosphere combine with water vapour to form sulfuric acid and nitric acid. Acid rain can damage forests, lakes, and streams, and can also corrode buildings and other structures.
* Climate change: SO2 is a greenhouse gas, which means that it can trap heat in the atmosphere and contribute to climate change.
* Health problems: SO2 can cause a number of health problems, including respiratory problems, such as asthma and bronchitis, and eye irritation.
To reduce the amount of SO2 in the atmosphere, a number of countries have implemented regulations that limit the amount of SO2 that can be released by power plants and other industrial facilities. These regulations have been effective in reducing the amount of SO2 in the atmosphere, but there is still more work to be done.
