Question

List three problems which arise due to construction of big dams. Suggest a solution for these problems.

Answer 1

Hint: A dam is an obstacle blocking or restricting the water flow or groundwater streams. Hydropower is also used to produce electricity in combination with dams.

Complete Answer:
A big dam may also be used for water collection or for water storage, and can be divided equally between areas. In general, dams have the primary function of water preservation, while other systems, like floodgates are used to regulate or restrict the flow of water to various regions of the country. The building of massive dams totally changes the interaction between water and soil, disrupting the current equilibrium of the environment, which has taken thousands of years to build in many instances.

Problems related to large dam construction are as follows:
A) Environmental challenge- Degradation leading to the depletion of habitats is one of the main repercussions of dam building. In the end, this is responsible for disrupting the natural ecosystem's equilibrium. Ever more trees should be planted to cope with this problem.
B) Social issue- Dam building will lead to flooding of neighbouring towns and villages. Because of this, a large number would become homeless. Proper compensation should be provided by the government to the injured citizens.
C) Economic problem-Building dams require an immense sum of capital. It is only after energy production begins that it becomes viable.

The suggestions for these problems are:
- More trees should be planted by individuals.
- Government should move residents to a secure location so they can resume their everyday job. If the lives of individuals are affected, the government must provide those individuals with appropriate compensation.
- Dam construction will be profitable if it is utilized for the production of electricity.

Note: There are actually about 40,000 major dams abstracting the rivers of the planet, completing a revolution in their circulation structure without severe environmental effects.
