The long and short of it is that the nature of the activity is inherently dangerous.
In SCUBA we were told "The safest way to dive is to not dive at all." but that, obviously is taking it too far.

The safest way to dive is to make yourself aware of all the potential dangers and take actions that will remove the hazard or reduce the risk.

One of the most effective actions is to dive with a buddy.

So unless you are taking enough action to remove/reduce risks to a satisfactory level then you should dive with a buddy.
