Answer:
Humans using water to generate electricity does not negatively affect groundwater.
Explanation:
Rainwater, which is mostly fresh, drains into sewers most of the time of course. They are abundant in many towns, cities, etc. As a result, rainwater is not utilized enough, as it goes to waste when blending in with dirty sewer water. This leads to rainwater not draining into aquifers, And with the worlds population increased rapidly by the minute, consumption increases, leading to the water contained within aquifers to decrease in amount. Runoff from things such as pesticides and fertilizers is also a major issue that harms groundwater. As rain approaches, these chemicals can seep through dirt and soil, eventually going as far as to reach the groundwater underneath the surface, contaminating it. And humans utilizing water to generate electricity is more of a benefit to the environment. It is another effective way to get power, and is an alternative to fossil fuels. And using groundwater as a power source does not really affect the groundwater itself, so this is why the last option is correct.
