naval invasion

On the island off the coast of Herzliya, about a year ago, they witnessed a performance that had not been seen in the Mediterranean Sea for more than 300 years. Appearing was a gray whale 

Every summer, divers on the shores of the Mediterranean suffer from the stings of the wandering jellyfish, a jellyfish that migrated to the Mediterranean Sea through the Suez Canal. There are many other migrants who have crossed the channel and their impact on the marine environment is not a source of satisfaction for fishermen and marine researchers.

A completely different wanderer was spotted off the coast of Herzliya last year and attracted the attention of researchers all over the world, On the island off the coast of Herzliya they witnessed a performance that had not been seen in the Mediterranean Sea for more than 300 years. The one that appeared was a gray whale, members of its kind were hunted and exterminated, only a few representatives remained in the Pacific Ocean, representatives that, following the protection of the large mammals, multiplied and today constitute a healthy population.

Apparently the gray whale in the Pacific Ocean is a different subspecies from the one in the Atlantic, therefore it is estimated that the whale seen in Herzliya was a member of the Pacific Ocean population that took advantage of the melting of the ice in the Arctic Circle to migrate from the Pacific Ocean to the Atlantic Ocean and the Mediterranean Sea, after it was seen in Herzliya a gray whale was reported against The beaches of Spain (probably the same detail). The chance for a single individual (or a small population) to survive since the 18th century without being discovered... negligible.

So is the chance for a single individual to migrate from the Pacific Ocean through the Indian Ocean around South Africa. In order to migrate from the North Pacific Ocean to the North Atlantic Ocean, two main factors are necessary, the first: the possibility of passage is necessary - ice melting that will open the maritime passage from west to east, the second factor... a reason for migration: currents, food, etc.
It turns out that both factors exist: from year to year larger areas of ice melt and open the passage connecting the northern parts of the Pacific Ocean and the Atlantic Ocean. The crossings are characterized by currents directed to the east and thus tiny creatures are swept eastward - tiny creatures are plankton (zoo and phyto) that serve as the basis of the food chain in the oceans. In the wake of the tiny creatures migrate fish and mammals that until today were not in the North Atlantic or disappeared from it a long time ago.

This is probably the story of the gray whale seen on the shores of Herzliya, which took advantage of the melting of the ice in the Arctic Circle and followed the abundance and exit of new sources of food, since following the melting of the ice there is what researchers describe as a "marine invasion" that endangers the fish populations in the Atlantic Ocean.

The vanguard of the invasion is probably algae: (Neodenticula seminae) which belonged to the large group of phytoplankton, according to evidence from fossils there has been no algae in the Atlantic Ocean for 800 thousand years. Today there is an acceleration close to New York and the researchers define the opening of the passage through the ice as "opening Pandora's box", since many species that have moved from west to east will damage the marine balance and the equilibrium that exists in the Atlantic Ocean.

Upheavals in ocean life are documented by researchers from many research institutes and are studied as part of a project Climate Change Impacts on Marine Ecosystems: Research Results. Researchers participating in the project emphasize the danger "in the flow of species to the east" and say that the new migrants will compete with local species such as salmon, cod and others.

Because of the directions of the wind and the currents (to the east) the invasion is one-way, that is, from the Pacific to the Atlantic, unlike the whale that swims under its own power, the jellyfish that "loves" cold could not have arrived in any other way but only with the help of the currents in the Arctic Circle. Fossil evidence shows that the last time there was a species transition between the Pacific and Atlantic oceans was about two million years ago.

A period in which a major invasion occurred that completely changed the ecosystem in the North E. Atlantic. In addition to the western invasion, it was found that many species move north (when the water warms).

The number of fish species in the North Sea increased from 60 to 80 in less than 20 years, since one of the reasons for the publication of the report was the appearance of the whale in Herzliya, the researchers continue and refer to the Mediterranean Sea and say that because of the warming and because the Mediterranean Sea is a closed basin where there are no cold lovers escape space. 75 species will be endangered and six will become extinct! In other words: in addition to the danger posed by the "Lessepsian invasion" (through the Suez Canal), in addition to the wild fishing that harms fish populations, warming is a real danger to life in the Mediterranean.

Is it necessary to mention that the time has come that instead of controlling the environment for the sake of the human population, there will be control of the human population for the sake of the environment!
