Answer: Filtration of pollutants
Explanation: The filtration of pollutants is not a way by which the energy producing technologies will affect the aquatic viability.
This is because removing the pollutants from water will improve the overall quality of water and it will not affect the viability of water. The flowing water or still water is highly polluted and it affects the aquatic life adversely.
To conquer these problem filtration of pollutants is necessary and this technique removes all the pollutants from water and makes the water clean without affecting its viability.
