Thermal pollution negatively impacts aquatic ecosystems by altering water temperature, which can harm fish and other aquatic organisms. Elevated temperatures can lower dissolved oxygen levels, disrupt breeding cycles, and decrease species diversity. Furthermore, thermal pollution can encourage the proliferation of harmful algal blooms, which further degrade water quality and threaten aquatic life. Addressing thermal pollution is therefore critical to maintaining healthy aquatic environments and ensuring the survival of various species and the overall health of ecosystems.
