Which is the most pragamatic strategy for restricting global warming?a.None of the aboveb.Stoppage to hydel power plant constructionc.Afforestationd.Prevention of bore well usage

The most pragmatic strategy for restricting global warming from the given options is c. Afforestation. Here's why:

1. Afforestation: This is the process of planting trees to create a forest on non-forest land. Trees absorb carbon dioxide, a key greenhouse gas that contributes to global warming, and release oxygen. This makes afforestation a very effective strategy in the fight against global warming.

2. Stoppage to hydel power plant construction: While it's true that hydel power plants can have negative environmental impacts such as habitat destruction and methane emissions, they also produce renewable energy that is much cleaner than fossil fuels. Therefore, stopping their construction may not be the most effective strategy for restricting global warming.

3. Prevention of bore well usage: Bore wells are used to extract groundwater. While overuse of bore wells can lead to a decrease in water levels and other environmental issues, it doesn't directly contribute to global warming. Therefore, preventing bore well usage is not the most effective strategy for restricting global warming.

4. None of the above: This option suggests that none of the strategies listed would be effective in restricting global warming. However, as explained above, afforestation is a very effective strategy.

Therefore, the most pragmatic strategy for restricting global warming from the given options is afforestation.
