Acid rain is a type of rain or precipitation that has a higher level of acidity than normal rainwater. It is caused by the emission of pollutants into the atmosphere, primarily sulfur dioxide (SO2) and nitrogen oxides (NOx), which react with water, oxygen, and other chemicals to form acidic compounds. These compounds can then fall back to Earth as acid rain, snow, fog, or mist.
Acid rain can have a number of negative impacts on the environment, including damage to plants and crops, destruction of forests and aquatic ecosystems, and corrosion of buildings and infrastructure. Acid rain can also have harmful effects on human health, including respiratory problems, skin irritation, and eye irritation.
Efforts have been made to reduce the emission of pollutants that contribute to acid rain, such as through the use of cleaner energy sources and the implementation of environmental regulations. However, acid rain remains a significant environmental issue in many parts of the world.
