Answer 2

Answer:

The conservation of fresh water would be the "most energy-efficient way" to make sure the "planet has adequate water" for drinking.

Explanation:

• Freezing ocean water, in the first place, would not be a good option as the ocean water would still be saline even after freezing it.

• On the other hand, it would neither be feasible nor would it be economical to freeze the ocean water.

• Though reverse osmosis and distillation are efficient methods of water treatment, it would not be possible to treat water enough to fulfill the drinking water need of the entire planet.
