> In addition to the challenges posed by these high pressures, FDs have no access to oxygen (O2) as they are underwater in a hypoxic (no O2) environment. Am I missing something, or is this the most unnecessary statement you could possibly make in an article about free diving? I think most readers know you can't breathe underwater.

And to add to the confusion, there is actually "hypoxic water" which is water containing no oxygen and is harmful to marine life.

  It can be quite dramatic. Fish can die almost instantly if they traverse the boundary.

It feels like it might have been written by AI. The cadence of the text is really unnatural.

Apparently the author is fresh out of B.Sc. She may not have much practice with writing pieces like this. (Daniela is a recent B.Sc. graduate from the program of Physiology at McGill. She is very passionate about understanding the human body and how we can all individually adapt our daily lifestyles to improve its functioning. Part of the OSS mandate is to foster science communication and critical thinking in our students and the public. We hope you enjoy these pieces from our Student Contributors and welcome any feedback you may have!) Another, more disturbing, possibility is that she could be right to include it for some of today's lay audience. I am seeing staggering levels of ignorance about chemistry in media here. Latest example being a radio anchor who had obviously never encountered the word cadmium in her life and made a very awkward (and failed) attempt to sound her way through it.

On further consideration, I think it's reasonable to remind people that free diving doesn't involve oxygen tanks, as the article had mainly been talking about only about the difficulty of dealing with pressure up to that point. It's a weird sentence, but makes more sense when read like "... and on top of being crushed by the water pressure, they don't have oxygen tanks either".
