Säureregen, or acid rain, is a type of precipitation that contains higher levels of sulfuric and nitric acids. This phenomenon occurs when pollutants from sources like factories and vehicles are released into the atmosphere. These pollutants mix with water vapor and can fall to the ground as rain, snow, or fog, leading to environmental damage. The effects of Säureregen can be harmful to ecosystems, as it can lower the pH of soil and water bodies. This change can negatively impact plants, fish, and other wildlife, disrupting their habitats and food sources. Efforts to reduce emissions from industrial processes and automobiles are essential to mitigate acid rain.
