There are large numbers
of caves located across the world. It is too difficult to explore many
caves due to unbearable weather conditions, sharp rocks, scalding water, and
slipping conditions in the caves.
Some of the underwater
caves in the world are even uninhabited by marine life because of deadliest
conditions. The flooded, Yucatan Cenotes cave network in Mexico is the best
example for it. The crystal caves and snow caves also become too dangerous for
expedition due to unprecedented changes.
