Answer:
Ground water will not be depleted in case of
Afforestation
This is because of the following reason :
- Afforestation refers to planting of various types of trees over a particular area.
- This allows water (falling on ground due to precipitation) to percolate within the soil.
- This prevents surface run-off of water
- If also helps in recharging or refilling the ground water level.
- Hence the water table rises up and clear , uncontaminated water is available.
But, in all the other given options, ground water will be depleted because, it leads to enormous use of water.
- Thermal plants use water as coolant
- Deforestation results in surface run-off
- Excessive cropping requires water.
So, option A) is the correct option.
