Here's why:
* Limnology is the study of inland waters, including lakes, rivers, and streams.
* Acid rain directly impacts the chemistry of these water bodies, making them more acidic.
* Limnologists specialize in understanding the ecological interactions within these aquatic environments, including the impact of pollutants like acid rain on fish populations.
While other biologists might have some involvement, limnologists are the experts specifically focused on these freshwater ecosystems.
