It is currently processed through solar panels or a similar system, but we could also recycle the artificially heated water for power in other ways in a secondary process. Thermal pollution cannot be overlooked as a potential threat to the environment.
What is Thermal Pollution?
Thermal pollution is pollution caused by adding heat to an ecosystem which adversely impacts the ecosystem. The U.S. Geologic Survey’s report Estimated Use of Water in the United States in 2005 estimates that power plants and industrial facilities withdraw approximately 219 billion gallons of cold water per day from surrounding ecosystems.
Why is warmer water bad for the ecosystem?
Why is warmer water so harmful to ecosystems? For starters, a warmer water temperature results in less oxygen in the water than in cooler water. The lack of oxygen kills fish and other aquatic species, while at the same time promoting anaerobic conditions that enable bacteria to thrive.
How does heat affect marine animals?
This is because waste heat from the cooling process in power stations and power plants generates and discharges warm water, which in turn decreases oxygen levels, killing fish, changing the composition of food chains, and reducing the biodiversity of the ocean ecosystems. Furthermore, higher water temperatures reduce the capacity for oxygen to reach deeper waters, majorly decreasing the water quality for aquatic species. This creates anaerobic conditions which are more suitable to bacteria, shifting the balance of the food chain and overall ecosystem.
