Environmental aspects must be carefully looked into before building huge dams. Discuss.

The dam is built as the barrier to the flowing of water. It is constructed as the reservoir and it mostly improves the irrigation facility of the area. According to the height, dams can be categorized as large dams and major dams or on the other hand as low dams, medium height dams and high dams. But the construction of dams can have a various environmental impact. Various problems associated with the constructed of large dams are:

• Wipes out all flora and fauna

When the flow of water is stopped by building dams then mostly the aquatic lives will be affected. The living things in the river will be completely spoilt.

• Increases the chances of the flood

When the whole water is stored in one place, then the water will be overflowed and if the dam's capacity is meagre then there are also chances for cracking and breaking down of dams.

• Chances of triggering an earthquake

There are places which have been experienced the earthquake, flood and other natural calamities because of the construction of dams.
