Cave Diving
Being underwater in dark and dangerous conditions is something that is dangerous in and of itself, even for the most experienced professional divers out there. Potential issues with oxygen and the creatures that live in the sea are just the tip of the iceberg with this sport.
With a minimal margin for error, little to no visibility, and freezing temperatures during these nighttime dives, lack of oxygen is only one of the many things you have to be worried about if you choose to engage in this sport. These caves are often unstable environments, but with the recent issues with fracking and sinkholes, there is no telling what the geography underwater might do.
