How much fish died because of acid rain?

Quantifying the exact number of fish that have died due to acid rain is challenging, as it varies by region, species, and environmental conditions. Acid rain can lower the pH of water bodies, making them too acidic for many fish and aquatic organisms to survive. Studies have shown that acid rain has significantly impacted fish populations in affected areas, particularly in regions like the northeastern United States and Canada, where many lakes and streams have experienced increased acidity. Overall, while specific numbers are difficult to determine, the ecological consequences of acid rain on fish populations can be severe.
