Question

Whoever good at science please help Which impact is the greatest negative of a new hydroelectric dam? A. air pollution B. changes in the surrounding landscape C. nuclear waste D. non-point source pollution

Answer 1

Hello!

The greatest negative impact of a new hydroelectric dam is the changes in the surrounding landscape.

Hydroelectric dams are among the cleanest energy sources, they don't generate waste, pollutants or atmospheric emissions. The negative impact is given by the landscape transformation needed to take advantage of the natural conditions of the dam. They stand out wherever they are, so it is important to consider the aesthetic aspect when building a dam. 

Have a nice day!
