Why can't you drink antarcticas water?

Answer 1

African and Arabian countries have also been asking this question. Turns out that the problem is logistical.

Towing an iceberg across the Equator means that the iceberg won't survive the journey.

Answer 2

The fresh water in Antarctica is potable but it is beneath several hundred feet of overlying ice. I can't drink it because I am unwilling to spend the thousands if not millions of dollars that would be required to drill down to it. That doesn't mean that some eccentric millionaire won't spend the money to be the first to do so.

Another Answer

People in Antarctica drink either melted ice or desalinated sea water. So yes, you can drink water in Antarctica, but not sea water.

(Note: Under the ice shelves, the sea water is too salty to drink.)
