Why would it be impossible to breathe air through an extra long snorkel while swimming underwater? Full face snorkel masks cover the entire face, allowing snorkelers to breathe out of their nose and mouth.
Full face snorkelling masks are not designed for leaving the surface to dive underwater, freediving, spearfishing, extensive open water swimming, or swim practice. With a full face snorkel mask you breathe the same as you would normally.
The mask covers your whole face hence being called a full face mask so that you can breathe through both your nose and mouth. Pride of Maui recently banned full-face masks from its snorkel tours, citing the potential dangers of carbon dioxide build-up leading to dizziness, headaches or unconsciousness. The company says on its website that this can also happen with poorly designed standard snorkel tubes. During busier swimming sessions or those with lanes, the use of snorkels can restrict the vision of the wearer as their head is predominantly face down in the water and this can cause accidents and injuries to other users in the pool when the wearer inadvertently collides with them.
While breathing we produce carbon dioxide. If you breathe in used air full of CO2 leads to headache, dizziness, and unconsciousness. COd up in wrong-designed normal snorkel tubes too… This problem can occur not only with full face masks, having the wrong equipment can always lead to dangerous situations. For beginners a full face snorkel mask can really be a boon.

In the attempt to get it under control you manage to plow the bottom and zero the visability. You now have a non-working scooter, you're 4,' back from the entrance, you have a decent idea of where the line is but you're not on it and you can't see. On OC this is a life-threatening emergency.
There are no trade-offs without costs; all "good" comes with a "bad. I remembered this again after my 75th dive, didn't pay attention to tidal predictions, was at fsw in a strong down welling, clawing at the sand and praying for my life. This began the next phase of taking it all much more seriously.
Repetition insures good habits, but eventually repetition can lead to going through the motions which can eventually lead to thinking you've gone through the motions when you actually haven't.
The folks who bite it in this sport are often the most experienced, and even on relitively routine dives. My suspicion is that over time the key to safe rebreather diving is keeping habits from becoming too second nature and always being prepared to deal if things go south.
