Hello! Hope you're having a great day, I'm looking at videos of underwater diving! 
how fun! It's so cool to be able to descend below the water's surface to interact with the environment
Yes! I agree so much, I would love to go underwater diving, have you been?
not yet. You see humans are not physiologically and anatomically well adapted to the conditions of diving so i'm a little bit scared
I'm a bit scared as well, that's why I'm looking up videos so I can learn more. :)
lol i would rather watch videos :) the diver is directly exposed to the pressure of the surrounding water 
I'll watch videos for a long while until I'll ever be comfortable ha!
you should know that the environment exposes the diver to a wide range of hazzards!
Thank you for the warning, I will prepare myself for that. I'm most interested in seeing how the oxygen exchange works in the mask.
diver is directly exposed to the pressure of the surrounding water. The ambient pressure diver may dive on breath-hold, or use breathing apparatus for scuba diving or surface-supplied diving, and the saturation diving technique reduces the risk of decompression sickness (DCS) after long-duration deep dives. Atmospheric diving suits (ADS) may be used to isolate the diver from high ambient pressure. Crewed submersibles can extend depth range, and remotely controlled or robotic machines can reduce risk to humans.

Underwater diving
Underwater diving, as a human activity, is the practice of descending below the water's surface to interact with the environment.
Immersion in water and exposure to high ambient pressure have physiological effects that limit the depths and duration possible in ambient pressure diving. Humans are not physiologically and anatomically well adapted to the environmental conditions of diving, and various equipment has been developed to extend the depth and duration of human dives, and allow different types of work to be done.
In ambient pressure diving, the
