Since the first sailors, humanity has sought answers that explain the principles on which the nature of the seas is based and which rule that takes place below their surface. Before the need ofhttps://en.yumping.it/en/diving href=https://en.yumping.it/en/diving href=" href="https://www.yumping.it/diving"> immerse yourself , a deep knowledge of navigation is born tohttps://en.yumping.it/en/diving href=https://en.yumping.it/en/diving href=" href="https://www.yumping.it/ sail "> sail or through the strength that man was able to produce through the oars.
It is possible that one of the finalities of his interest was the exploitation of the infinite resources that the sea offered. Collecting and fishing numerous species to be commercial, both for food and ornamental use in the creation of jewelry and various objects, has always been the aim of many peoples on the coast.
We find the most ancient tests in the remains of the prehistoric deposits, in sponges caught byhttps://en.yumping.it/en/diving href=https://en.yumping.it/en/diving href=" href="https://www.yumping.it/diving"> sub of Crete, pearls and corals marketed in Egypt since 3500 B.C. O mother -of -pearl of India that was sold in the Mediterranean since 1200 BC
From this facet of sailor stands the need to recover the remains of the ships which, for very different causes, went to peak or part of their load ended up at sea. When this happened in shallow waters, many ventured in an attempt to recover the load. And it was very complicated when they had to resist under several meters of water without breathing.
We must not forget that the first dives mainly had military character . The attack on enemy ships without being detected by the soldiers required a very cautious approach under the hair of the water.
Other scholars say that the attraction that the sea on man exerts derives from the need to return to his origins. The origin and evolution of the species on earth derive from a transformation during millions of years of the forms of life proceeding from the seas. This ancient origin can explain the attraction that, always, man has tried to discover that he hides under water.
Our nature as mammals involves that a continuous spare spare of the air that we breathe is necessary for our survival. The waters that make up the seas are not our natural environment and, therefore, the first underwater incursions were limited to short periods in which breathing in apnea was outlined. Another very important inconvenience It was the scarce visibility due to the refraction of light under water, which enormously complicated the collection of objects and the capture of fish with arrows and spears.
The large path that traced the evolution of techniques and immersion materials has been starting before 7000 years and continues every day with new improvements ...
Although currently we are still far from the colonize the underwater seabed , in the future numerous and incredible discoveries will be produced in the conquest of the submerged depths that will expand the limited time of permanence we currently have.
