What are the advantages and disadvantages of dams to the society and environment?
Comparison Table for Advantages and Disadvantages of Dam
| Advantage of Dam | Disadvantage of Dam |
|---|---|

| Widely used for irrigation and cultivation purposes | It can lead to higher greenhouse gas emissions |
How the construction of large dams cause economic and environmental problems?
Dams hold back the sediment load normally found in a river flow, depriving the downstream of this. In order to make up for the sediments, the downstream water erodes its channels and banks. This lowering of the riverbed threatens vegetation and river wildlife.
