Under Water

摘要

With a 361 million square Km surface and a volume of 1370 million of cubic kilo, world seas and oceans have represented and still remain the privileged space for living species evolution. Other than being the 70% of the Earth surface, water environment, contrary to the terrestrial one where life essentially develops in 2 dimensions, is a 3D fully volume for leaving. This circumstance makes the under water world a huge space of nature mankind exploration. Modern man thinks to already know most of thesecrets of the universe, although it was not able to process a planet to make it livable (a new planet of reserve), or at least to discover the secrets of the universe or of the small universe, or those secrets from the depths of the ocean planetary. Under water exploration, by facing some of the most amazing creatures of the sea and by understanding their unique evolutionary path, improves our knowledge of life evolution while clarifying the impact of the global climate changes on these delicate ecosystems. This work presents some considerations related to the seas and oceans possible future mankind interactions with the "Blue Planet". Retrieving materials and energy from underwater world is discussed.
