Answer 2

Answer:-

$.$

Hydro power is increasingly being promoted as a renewable source of energy with low emissions of greenhouse gases, capable of being produced at a scale necessary to meet pressing energy demands with current technology. With heightened global concern about energy security and climate impacts, hydro power is extremely attractive. In rapidly developing countries such as China, the availability of immense hydroelectric resources is seemingly irresistible. With its strong economic growth being highly dependent on reliable electrical energy, and with its severe problems with air pollution, China will almost certainly build a large increment of new hydro power.

However, hydro power doesn't come without significant environmental costs. In general, freshwater ecosystems and species are among the most highly threatened in the world.
