For many centuries in all people and peoples of this cry had the same sense of alarm: “From the man was a trouble! Help me! “In the future, mankind will give those words a different meaning. Constantly increasing world population will become more and more closely within the land, and it goes into the sea – will win at the sea of space for their settlements.

From this table it is clearly visible uneven distribution of water resources in natural areas of the planet. A specific locations on Earth, these differences may be much higher.  For example, in India there is a meteorological station Cherapundzhi, where the annual rainfall record rainfall – 23 mm thousand, and in Peru at weather stations in La Zhoya did not get a single millimeter of rain per year. Therefore, on Earth as many other deserts I drylands. Whole areas where prosperity, or even in excess of a variety of natural resources – the sun’s heat, fertile and suitable for the cultivation of the soil – has not enough water, precipitation.

The remains of living organisms, dead in the upper layers of the ocean, passing through the twilight zone of intermediate depths, then settle in the dark as a moonless night, deep ocean water column. Drops of this unfortunate “Rain” are almost the sole source of food for local inhabitants.

It is known that in today’s oceans are home to over 160 thousand species of animals and about 10 thousand species of algae. This number is constantly growing, so-called in studies in the ocean regularly found more and more new species and varieties of living plants and animals. Only during the expedition to the Challenger, which was already mentioned above, it was discovered 4,417 unknown to science species of marine organisms, which increased the number of species known at that time, several times.

The ancestors of the biggest animal on Earth – China – about 70 million years ago are gone from the land into the water. Gone, because in the sea, they found a much better habitat conditions. ”Wisdom” China is explained simply – here, in the ocean, filled to the brim with food, whale offspring daily adding to the weight of ten pounds, is fast becoming a multi-ton colossus, and then peacefully there for many years, the fruits of their own kind.

Yes, yes, plain water – it’s too precious a treasure! With the increasing world population and continued development of the production of people every year more and more convinced of this, radical way to solve the water problem could be the development of virtually inexhaustible supplies of seawater. Our country is one of the first to seawater desalination. , Russia’s first desalination plant was established back in 1881, in Krasnovodsk. Now worldwide, not counting the small desalination on marine vessels, has been working for about a hundred of large desalination plants.

One of the most interesting to unravel the mystery and XX. scientists call the discovery of underground “seas” – a vast reservoir of fresh or brackish water in porous rocks under the desert. They lie at different depths. So, in the Kara Kum desert upper limit of the underground “sea” is at a distance of 30 m from the ground, in the Sahara – 150 -200 m. Underground Sea still poorly understood by science, and still in their “behavior” more questions than answers. For example, it is known that the level of the water surface fluctuates constantly, but for whatever reason and at what intervals occur groundwater inflow and ebb – it’s science is still unknown.

One of the most ambitious, of unimaginable complexity and at the same time amazingly beautiful structures created by living creatures on Earth, are the coral reefs and coral islands – the atolls. Largest atoll in the mass than any of the structures erected by man in history!

There are many examples of geographical “closed” in the vast oceans. Especially a lot of them had to do in his priantarkticheskih waters.

For several reasons. First, it incorrectly identifies the position of an object in the ocean.Secondly, the icebergs were deceptive appearance. A perfect example of the first – Bouvet Island. This single rock has been turned by sailors of centuries past in a arhipelag.Kitolovy, maneuvering in dense fog, could only roughly determine its position in the ocean.  Therefore, returning repeatedly to the same place, they are unaware that taking the land in sight for the new island and each time it was applied to the card.
