The global salt cycle in nature is disrupted, which leads to salinization of fresh water, and the distribution of salt by ocean currents plays a role in regulating surface water temperature and sea level.<\/p>\n


\nEcologists have found that humanity releases into the environment approximately the same amount of salts that enter ecosystems from natural sources. This disrupts the global salt cycle in nature and leads to salinization of fresh water, the press service of the University of Maryland at College Park (UMD) reported. The collected information suggests that the global salt cycle, which involves both the Earth’s interior and its atmosphere, has been seriously disrupted as a result of human activity.
\nAn analysis carried out by scientists showed that humanity releases huge amounts of table salt and fertilizers into aquatic and land ecosystems. They are comparable to the original mass of metal ions, chlorine, phosphoric, nitric and sulfuric acid, as well as other components of mineral salts present in nature untouched by humans. For example, approximately 271 million tons of table salt have been identified in rivers in the United States, about 70% of which is of natural origin, while the remaining 30% comes from anthropogenic sources.
\nThe two largest of them are industrial salt (13.9%), used to clear roads of ice and snow, and compounds that are used to fertilize and cultivate fields (6.7%) and from there end up in groundwater and rivers.
\nThe rapid growth of this anthropogenic pollution has led to disruption of the natural salt cycle and its accumulation in groundwater and soils over an area of \u200b\u200bapproximately 10.12 million square meters. km, which is comparable to the size of the largest countries in the world. At the same time, the concentration of sodium and chlorine in large rivers has doubled compared to the middle of the 20th century. A further increase in salt concentration will lead to serious consequences for plants, animals, infrastructure and human health.

For example, salinization of the Azov Sea caused an outbreak in the number of yellow jellyfish. According to Natalya Milchakova, head of the phytoresources laboratory of the Federal Research Center \u201cInstitute of Biology of the Southern Seas named after Kovalevsky,\u201d their reserves \u201chave increased by orders of magnitude.\u201d This leads to the disappearance or reduction of the food supply of many species of fish, she explained at a press conference at the press center of the Rossiya Segodnya news agency in Simferopol.<\/div>\nNew research from the GEOMAR Helmholtz Center for Ocean Research in Kiel provides evidence that reduced salt movement into high northern latitudes will intensify and prolong cold climate anomalies. Conversely, the slow movement of positive salinity anomalies from the tropics will ultimately lead to an increase in the density of surface waters in the subpolar North Atlantic. This could help ocean currents transport heat northward, leading to milder temperatures over Europe and North America.<\/p>\n
