Question

why are large dams under scrutiny these days and explain the ill effects caused by their on the environment.​

Answer 1

Answer:

1. Land and water are ecologically linked in a natural system called a watershed. From the smallest droplet to the mightiest river, water works to shape the land, taking with it sediment and dissolved materials that drain to watercourses and, in most cases, eventually to the sea. So, too, is the river a product of the land it inhabits––the type of rock and soil, the shape of the land, and the amount of vegetation are some of the factors that determine the river’s shape, size and flow.
