Acid rain can have detrimental effects on aquatic ecosystems. The increased acidity from acid rain disrupts the natural pH levels of water bodies, leading to harmful conditions for aquatic life. It can negatively impact fish and other organisms by reducing their reproductive success and causing health issues. Moreover, acid rain can release toxic metals from sediments, further harming aquatic organisms. These changes can reduce biodiversity and alter food webs in affected environments, showcasing the far-reaching environmental impacts of acid rain.
