Despite the constant modernization of modern life, it is impossible to separate man from nature. It is all the more impossible to imagine a person separated from the water world. The oceans occupy 2/3 of the surface of our planet, it not only became the cradle for its nascent life, but also serves as a source of constant support for all life on Earth. Man is no exception to this rule. Modern humanity is very closely dependent on the resources of the World Ocean.
The ocean supplies man with many useful biological resources. Fishing is one of the oldest trades that remains relevant to this day. Fish and seafood are one of the healthiest foods in the modern human diet. From the same seafood and algae, extremely useful components are released, which are actively used in the cosmetic and medical industries.
The ocean contains rich mineral resources. Among them are the deposits of minerals at the bottom and under it, and the ocean water itself, which contains many substances that are actively used by humans. The reserves of ore, oil, gas and coal on the ocean floor significantly exceed those on land. It is underwater mineral resources that represent the present and future of the modern mining industry.
It is not for nothing that ocean water is called "liquid ore" - it contains a spectrum of elements from table salt to gold. Of course, gold is not extracted from water, its concentration is too insignificant, but the release of table salt, magnesium and bromine is on an industrial scale. The main advantage of the extraction of mineral resources from ocean water is its economy and unlimited raw materials.
The ocean contains a huge energy potential. The energy of ocean currents, ebb and flow, significantly exceeds the potential of all rivers on our planet. However, at present, this potential is just beginning to be developed and so far it is being used insufficiently. Tidal power plants have already been built in Japan and Europe. They are highly effective, but quite expensive.
In addition to quite tangible material resources, the ocean offers a person a special world that allows you to change your view of the surrounding reality, get rid of the consequences of the stresses of everyday life, and restore strength. It is the proximity to the ocean that makes it possible to remember the unity of man and nature.
