Acid rain is a serious environmental issue that can have devastating effects on ecosystems and human health. It is caused by the release of sulfur dioxide and nitrogen oxides into the atmosphere, which react with water vapor to form sulfuric acid and nitric acid. These acids can then fall to the ground in rain, snow, or fog, damaging forests, lakes, and buildings.
There are a number of things that can be done to avoid acid rain. One is to reduce the emissions of sulfur dioxide and nitrogen oxides into the atmosphere. This can be done by using cleaner energy sources, such as solar and wind power, and by improving the efficiency of energy use. Another way to avoid acid rain is to plant trees, which can help to absorb sulfur dioxide and nitrogen oxides from the atmosphere.
