Impact of Acid Rain on Environment

The video explains acid rain, its formation, and its effects on the environment and human health. Acid rain forms when sulfur dioxide and nitrogen oxides react with water and oxygen in the atmosphere. While not directly harmful to humans, the pollutants can cause respiratory issues. Acid rain significantly impacts aquatic ecosystems, soil, and infrastructure, leading to ecological imbalances and material corrosion. The video encourages viewers to consider the broader environmental implications and engage in discussions.
