Question

Yall Im struggling, if u cant read it, the question is “why does a mountain climber need an oxygen supply at very high altitudes, even tho the air still contains 21% oxygen?

Answer 1

Answer: Because it is harder to draw breath in. And the cold

Explanation: At higher altitudes, it becomes more dangerous, and you can develop altitude-related illnesses such as HAPE and HACE. I read a book called Into Thin Air, and in the book the author goes into detail on the details/complications of climbing Mt.Everest and oxygen needs. Mountain climbers use canisters of oxygen called Supplemental Oxygen.
