Question

why is thermal pollution a problem?
hot chemicals are dumped into oceans which kill tiny organisms.
hot water from power plants is dumped in lakes which decreases oxygen in the water and kills fish.
due to global warming, the sun is heating up lakes and fish cannot survive at hot temperatures.
thermal pollution is actually good for the environment.

Explanation:

Thermal pollution often occurs when hot water from power plants is discharged into bodies of water like lakes. This raises the water - temperature which decreases the dissolved oxygen in the water, harming aquatic life such as fish. Hot chemicals being dumped is chemical pollution, not thermal pollution. Global warming is a different concept from the direct impact of thermal pollution from power - plant discharges. Thermal pollution is not good for the environment.

Answer:

Hot water from power plants is dumped in lakes which decreases oxygen in the water and kills fish.
