Question
Of all the water on the earth, only about 3% is fresh water. 68% of all the freshwater is frozen as glaciers and is unavailable for human consumption. We have the technology to desalinate the ocean water to make it drinkable. Why is it that we do not desalinate water on a large scale to increase the total amount of fresh water available for humans?

A The desalination process is too expensive to do on a large scale.The desalination process is too expensive to do on a large scale.
B We cannot make the salt water clean enough for human consumption.We cannot make the salt water clean enough for human consumption.
C We currently desalinate tremendous volumes of ocean water for humans.We currently desalinate tremendous volumes of ocean water for humans.
D There is no need for desalination as humans can safely drink ocean water.

The most accurate response to the question would be:
**A** The desalination process is too expensive to do on a large scale.
While desalination technology exists and is used in some regions, the high costs associated with the process, including energy requirements and infrastructure, make it less feasible for widespread adoption compared to other sources of freshwater.
