Question

Opposition to the construction of large dams is due to

• A. Social reasons
• B. Economic reasons
• C. Environmental reasons
• D. All of the these

Answer 1

The correct option is D

All of the these

The correct option D:
Explanation of the correct option:

1. Significant dams are costly to construct and, if erected in a mountainous area, result in the submergence of significant sections of natural forests, the displacement of a large number of indigenous people, and the risk of earthquakes and landslides.
2. As a result, large dams have substantial environmental, social, and economic costs, and all of these considerations should be carefully considered prior to the construction of a new dam.
3. Large dams also encounter opposition as a result of all of these social, economic, and environmental challenges.

Option A:

Social reasons:

1. The relocation of an enormous number of native individuals happens because of the development of a dam in a sloping territory inclined to tremors and avalanches, who then become homeless.
2. Sufficient compensation or rehabilitation is not provided to them and from these projects, they don't get any profit.

Option B:

Economic reasons:

1. At a very high cost, large dams are built that result in a decrease in the economy, and large areas of natural forest get submerged.
2. For the losses, people are not given the required compensation which results in economic problems like temporary unemployment for people.

Option C:

Environmental reasons:

1. Dams are liable for disturbing the biological system's harmony and the connection between water and land, which required millennia to create.
2. It causes land disintegration, which pulls back the residue load that usually happens in a waterway stream and brings down the riverbed, jeopardizing verdure and waterway fauna.
3. Dams in tropical climates allowed mosquitoes and other vectors to breed, which carry malaria and cause Schistosomiasis and river blindness due to their slow movement.

Final answer: Opposition to the construction of large dams is due to social reasons, economic reasons, and environmental reasons.
