Question

of the following choices, which is the best way to help earths water supply last for future generations?

a. build thermal power plants.

b. avoid drip irrigation systems on farms.

c. promote private swimming pool construction.

d. reduce residential water use. .

Explanation:

• Option A: Building thermal power plants typically consumes large amounts of water for cooling, which would deplete the water supply rather than help it last.
• Option B: Drip irrigation is an efficient method that reduces water waste in farming. Avoiding it would lead to more water being used, so this is not helpful.
• Option C: Promoting private swimming pool construction would increase water usage for filling and maintaining pools, which is wasteful for water conservation.
• Option D: Reducing residential water use (like shorter showers, fixing leaks, etc.) directly decreases the demand on the water supply, helping it last for future generations.

Answer:

D. Reduce residential water use.
