There are certain disadvantages associated with the construction of dams across rivers.

Environmental problems: The construction of dams across rivers leads to deforestation, which results in the

loss of biodiversity. This creates a disturbance in the natural ecosystem.

Solution: To compensate the deforestation, we should plant more trees.

Social problems: The construction of dams involves the building of large reservoirs. In some cases, constructing a reservoir may result in the flooding of nearby towns and villages. A large number of people are displaced as a direct consequence of the construction of reservoirs. In such cases, the government rehabilitates the people of these areas, which in itself is a huge task.

Solution: Government should provide proper compensation to the affected people.

Economic problems: The construction of dams requires huge amounts of monetary investments.

Solution:

A dam becomes profitable if it is used to start generating electricity.
