« I won’t go to Chernoye! It's with bacteria!», « Oh! Yes, Azov is really dangerous!“- you say, but you can’t even imagine which sea is the dirtiest. Our Top 10 will help you figure out where the trumpets about a man-made disaster are about to be trumpeted (if they haven’t already done so).
Decline in fish production by 70% + dangerous tourists.
The waters extend over 438,000 km², and the sea is considered the saltiest in the world, because not a single freshwater river flows into it. The concentration of pollutants only increases (plastic bottles, bags, candy packaging), and the reservoir is “shredded” due to evaporation. According to some reports, the number of fish caught has decreased by 70%. The reason is simple: aquatic vertebrates simply die under the dominance of plastic and polyethylene.
9. Caspian Sea
Increased concentration of phenol + mass death of sturgeon.
The largest endorheic lake with an area of 371,000 km² is dying under the yoke of oil rigs and barges. Just imagine that the concentration of phenol here is 6 (!) times higher than permissible standards. So far, the “black gold” miners are fighting off environmentalists and the public, continuing to pollute the waters of the Caspian Sea with processed products. Poachers who organize real hunts for salmon and sturgeon also add to the problems.
8. Sea of Japan
Oil stains on 90% of the bay area + the content of phenols and pesticides is 10 times higher than normal.
The waters wash the territory of 4 states at once (North Korea, Russia, the Republic of Korea and Japan), spreading over 1,062,000 km². This is not the dirtiest sea, but just imagine what it is like here:
- nuclear bases and submarines are buried;
- radioactive substances from “obsolete” warships have been conserved;
- particles of mercury, arsenic, phosphorus, nitrogen, lead float;
- the amount of hydrogen sulfide increases;
- full of petroleum products and dangerous phenols.
7. Laccadive Sea
Gutter of the metropolis + heavy metal content of 0.6 ml per 1 liter.
A reservoir with an area of 786,000 km² “neighbors” large populated areas, and this proximity is definitely not beneficial. Laccadia water is a test tube from a chemical laboratory, which contains radionuclides, carcinogens, arsenic, heavy metal salts, and mercury particles... Scientists are sounding the alarm, because the concentration of heavy metals in ports reaches 0.3-0.6 ml per liter This is 6 times higher than the maximum permissible values.
6. South China Sea
China's claims + threat of destruction of 121 reefs.
The reservoir, with an area of 3,537,289 km², bears the title of the dirtiest in the Southern Hemisphere. The key problem is China's desire to capture up to 86% of the space and build cities on reefs and rocks. Of course, sewage, chemical waste, oil particles, radionuclides will burst into the waves, and thousands of rare reefs will die. The threat is posed by climate change, agricultural fertilizer discharges, and fishing by poachers. A little more - and the title “The dirtiest sea in the world” is guaranteed.
5. Sea of Azov
Increase in the concentration of phenols by 7 times + man-made disasters!
The facility, with an area of 39,000 km², has been under threat of disaster more than once. If in Soviet times the sea was famous for its fishing opportunities, today environmentalists are sounding the alarm (aquatic vertebrates are dying due to carcinogens). The concentration of thiocyanates in waters is 12 times higher than the established standards. In some parts, the oil content exceeds the maximum permissible concentration by 150 times!
The problem is not only with enterprises that actively dump pollution into Azov. From time to time, dry cargo ships and tankers sink in the waters. For example, in 2007, just one of these accidents occurred. As a result, 1,300 tons of fuel oil were thrown into the sea.
4. Baltic Sea
500 tons of chemical weapons + annual 50 tons of cadmium.
An area of 415 thousand km² is a real “chemical/nuclear barrel”. Since 1951, the Baltic waters have been used for the burial of chemical weapons, charges and bombs. Over 60 years, the protective packaging has rusted, and all the “good” rises to the top. Enterprises and tankers/bulk carriers also add problems. Every year, about 33 tons of mercury per 21 thousand km3 are dumped into the waters. The amount of copper is 4,000 tons and more, lead is more than 3,000.
3. Mediterranean Sea
Up to 1,000,0000 tons of oil per year + 100 thousand tons of mercury.
Jacques Cousteau also called the waters a “garbage dump,” and today, on an area of 2,500,000 km², not much has changed. Are you planning to spend your holidays in Italy, Montenegro, France or Cyprus? Keep in mind that up to 1,000,000 oil and petroleum products are thrown into the Mediterranean Sea every year. WHO began to sound the alarm back in the 1990s, because 12,000 tons of phenols, 800,000 tons of nitrogen, and 3,800 tons of lead were dumped into the water area.
2. Black Sea
90% jellyfish + threat of man-made disaster.
The condition of the reservoir with an area of 422,000 km² is characterized as “ecologically unfavorable”. Viktor Tarasenko (President of the Crimean Academy of Sciences) stated that the Black Sea is the dirtiest sea in the world, and not just in Russia. The reasons for the problems are trivial:
- Nitrates and phosphates coming from agricultural land;
- water pollution with oil and petroleum products;
- human waste (just imagine that about 20 European countries dump wastewater here in one way or another);
- construction on the Black Sea coast (source of concrete, sand, asbestos, bricks, cement dust);
- poaching and fishing (experts from Great Britain came to the conclusion that the uncontrolled actions of “those who want to make money” led to a serious restructuring of the ecosystem at least twice in 50 years).
1. The Gulf of Mexico is the dirtiest sea
Not water, but a solid reagent.
The inland sea of the Atlantic Ocean with an area of 1,543 thousand km² is a whole “chemical laboratory!” The rivers of Cuba, the USA, and Mexico carry here the remains of agricultural fertilizers and sewage effluents. But this is not the worst thing, but periodic oil spills and explosions on drilling rigs and tankers. For example, in 2010, the largest oil spill in the United States occurred: more than 5,000,000 tons of barrels of “black gold” went into the bay, and an area of more than 75 thousand km2 was literally “scorched” (the fish died instantly).
If people want to relax on clean bodies of water, they need to remember about the environment!
Which sea is the dirtiest?
Ecologists cannot yet give a definite answer to this question. There are different types of pollution; the same sea can be clean on one coast and heavily polluted on another. So far, the dubious reputation of the dirtiest seas is shared by three water surfaces - the Mediterranean Sea, the Baltic Sea, and the Black Sea.
Mediterranean waters
Mediterranean Sea is the dirtiest in the world, according to the international organization Greenpeace, which conducted monitoring together with the Spanish Institute for Ocean Research. The waters of the Mediterranean Sea are especially polluted in the area of large ports of developed countries, such as France, Italy, and Spain. Every year, about 400 thousand tons of hazardous oil products and industrial waste are accidentally or intentionally discharged into the sea. And for every square km of the seabed, about 2,000 objects fall that are waste from human activity.
Moreover, plastic waste entering the Mediterranean Sea mainly from the coast poses a particular danger to flora and fauna. Some types of fish, especially tuna and swordfish, accumulate mercury, which is very dangerous for humans, so you should not eat Mediterranean seafood in large quantities.
The Gulf of Finland
Another problematic area of the sea in terms of pollution is the Gulf of Finland Baltic. Most of the harmful pollution comes from spilled petroleum products. In addition, the Baltic Sea itself is very dirty, its geographical location is to blame for this; the sea is surrounded on all sides by industrialized countries: Sweden, Norway, the Baltic countries. Baltic fish is also not very safe; it contains excessive mercury. The Baltic Sea is also polluted by industrial waste.
Troubled Black Sea
Black Sea is also present on this list of environmentally unfavorable reservoirs. Rivers from all over Europe flow into it, carrying all the waste of human activity. The Black Sea is polluted with oil products, especially affected by the Kerch accident in 2007.
The sea has an unfavorable ratio of surface area to water intake area, approximately 1:6, which has a bad effect on the rate of water exchange, and, accordingly, on the ability to self-purify. The situation is worsened by hydrogen sulfide, which lies in layers on the bottom of the Black Sea and periodically rises to the surface due to high summer temperatures.
Some exotic lovers, oddly enough, prefer to swim in dirty water. There are people who purposefully search for this type of “entertainment” on the Internet. And in Kuban, at the height of the velvet season, “dirty” tourism is gaining popularity. Last summer, many vacationers preferred extreme swimming in lakes of mud volcanoes to traditional relaxation on the beach and sea baths. By inheritance, the local Cossacks are engaged in the “dirty” business.
But still, fortunately, such originals are in a clear minority. Most of our compatriots, when planning to go to the coast, ask themselves the question: which sea should they go to in search of the most environmentally friendly sea bathing (bearing in mind popular tourist routes)? Oceanologist Nikita Kucheruk, Candidate of Biological Sciences, has compiled a “hygienic” rating of the seas, which we invite you to familiarize yourself with.
1. Seychelles and Caribbean islands
Secluded islands far from civilization are the best places for swimming. The water is perfectly clear. Near these islands the sea is very warm all year round, and there is very little food for marine life. So, if any product of human activity (domestic, oil pollution) gets into these heavenly blue waters, marine flora and fauna take these emissions as a pleasant addition to breakfast and sweep them away in an instant. Strong ocean currents near the islands help restore the ecological balance; the bottom, not far from the coast, abruptly drops into the depths - this also prevents emissions from stagnating. Although, in fact, there are few emissions: there is no industry, and the routes of oil tankers are far away.
2. Portuguese coast and Dead Sea
The Atlantic coast of Portugal is slightly inferior to the secluded islands. Low-waste industry, deep bottom and, moreover, the ocean - it is much more difficult to litter it than the sea. Along Portugal, the water is cleaned by a “branch” of the Gulf Stream. But it is not always safe to make long swims in the ocean, that is, it simply depends on the topography of the coastline. If there are reefs nearby and the depth of the water near the shore changes sharply, at high tide a strong undercurrent begins and the swimmer can be carried away into the open ocean.
As for the Dead Sea, it is also very clean, but there is no mention of any marine flora and fauna: the sea is so salty that no one lives there, no flowers, no fish, no algae. Yes, and you won’t be able to swim like a human being. True, the benefits from it, as we have already written, are immeasurable: not only the skin is treated here, but also rheumatism and depression.
3. Resorts of the Indonesian archipelago (Bali, Malaysia), Singapore, Australia
The beaches of Indonesia practically share an honorable second place with the Portuguese coast in our ranking. Tropical seas are very warm, and just like in the Seychelles, there is little food for marine life - so if some industrial waste gets into the water, the living creatures quickly eat it all up.
And at the same time, marine life is the only source of trouble. Communication with a jellyfish nicknamed the Sea Wasp with 5-6-meter transparent tentacles saturated with nerve poison will end in at least a burn.
Hated by snorkelers, sea urchins are found in great abundance. For example, it is better to stay away from the crazy handsome man nicknamed “diadem” - our expert oceanologist had personal contact with “diadem” and shared his impressions: “Like after a shelling.”
You also need to be careful with coral reefs: if you touch “fire” coral, at best you will get a burn (like after falling into a thicket of young nettles). On the beach you can come across a large cone-shaped shell of heavenly beauty, in which lives a mollusk - the owner of a deadly proboscis with which it kills fish. The person, of course, won’t fare well either. So it’s better to observe everything bright and beautiful from afar.
4. Eastern Mediterranean
An excellent place for lovers of ecological swimming and the freshest seafood: the sea there has hardly suffered from the costs of civilization. The Cretan and Greek beaches, as well as the Mediterranean beaches of Israel and Turkey, have the cleanest and most “living” sea in the entire Mediterranean. There is no industry, there are great depths around. A problem that the sea cannot cope with even in these areas is the frequent occurrence of plastic bags that do not decompose at all: the water is clear and they are clearly visible.
5. Mediterranean coast of Egypt
It would not have gotten a pass into our top five if the Nile had not actually stopped flowing into the Mediterranean Sea. About ten years ago, a plant called “water hyacinth” fell into the river, which quickly multiplied, and the Nile began to bloom. But this life-loving plant turned out to come from humid Florida, so it evaporates a lot of liquid, and in dry Egypt, water hyacinth, the bastard, evaporates all the remaining river water in large volumes, and all the rest of the water is used to irrigate fields and practically does not reach the sea - which and it’s good, because if it did, it would be with fertilizers. Thanks to such an environmental nuisance, the sea has become cleaner, and the water hyacinth is alive and well and has even adapted to the herbicide attacks of the Egyptian authorities.
6. Aegean and Red Seas
The Aegean Sea is relatively prosperous - due to the fact that the ratio of the catchment area (the entire area on land from where water is collected and flows into the sea) to the sea area is very favorable - 1:1, which means the proportion of industrial discharges is moderately modest. Swimming off the coast of Greece is not marred by any plankton, and freshly caught fish is very good.
Turkey's Aegean coast is becoming increasingly problematic, with sewage causing red tides to occur more frequently off the coast from Izmir to Istanbul. Layers of water rich in phosphorus and nitrogen rise from the depths of the ocean, because of which toxic (for both people and fish) microflora begins to rapidly multiply - the sea off the coast becomes brown-red in color. Tourists are not allowed to swim or eat seafood at this time, given the experience of local fishermen and swimmers: due to swimming in the sea during red tides, they lose a total of 10 thousand working days a year, as reported by Greenpeace.
Despite the proximity of the Suez Canal, through which oil tankers sail, the Red Sea quickly “digests” pollution, like any tropical sea, where there is a lot of “hungry” algae, fish and other inhabitants and little food. Oddly enough, an oil spill is also considered a good snack for the tropical sea ecosystem. For example, after an oil spill during the US military operation Desert Storm, the sea recovered in a matter of months (for comparison: the northern seas take five to seven years to recover from a similar shock). And the warning about brightly colored fish and jellyfish still applies: don't grab them by their fins or tentacles. Moray eels (a type of eel) that hide in rocks bite like young bulldogs.
7. Mediterranean beaches of France, Spain and Italy
The Mediterranean Sea, of course, can handle everything. Although France, Italy and Spain are the source of three quarters of industrial and agricultural pollution that enters the Mediterranean Sea. But soon the forces of self-regulation by the sea will be exhausted: Greenpeace is already sounding the alarm - each of the ten beaches in the area from Cannes to Capri does not comply with European Union standards. Not to mention the sad facts: last year, dolphins washed up on this part of the coast, and due to the ubiquitous tourists, the populations of animals living on the beaches - the Mediterranean turtle and seal - have decreased by two to three times.
And by the way, lately local wildlife has been coping with alien marine plants worse and worse. For example, off the coast of the French Riviera and Italy (from Toulon to the Italian town of Imperia), the sea weed Caulerpa taxifolia (native of the tropics) began to multiply at enormous speed due to sea pollution by sewage. This weed produces a toxin that kills deep-sea algae. In general, you won’t get poisoned by seafood in these areas, but still don’t eat a lot of it: they contain slightly higher levels of mercury and heavy metals.
8. Adriatic Sea, coast of Tunisia and California
In the waters of the northern Adriatic and off the beaches of Tunisia, there is more chlorophyll than normal - when the water temperature rises above 25-26 degrees, the sea may bloom. Along the coastline in these areas, water exchange is not intensive, and industrial emissions linger longer. This is precisely the effect of the “ring current” that exists in any closed sea: the current along the shelf (the flat coastal part, just where the beaches are) carries with it all possible pollution and does not allow them to mix with the deep sea layers.
The Adriatic Sea is in a difficult situation - along with the waters of the Po River, waste from the rapid Italian industry enters it: in the late 90s, the volume of discharges became ten times more than half a century ago. So you should not choose the closed bays and lagoons of Trieste and Venice for swimming (you will probably be impressed by the fact that tons of algae are caught from the Venetian lagoon every year so that they do not emit unpleasant odors).
In California, the clarity and smell of the water is much better. Why then is the famous Sunset Beach not at the top of our rating? Due to the increasing frequency of red tides, during which the famous California oyster farms have to be closed.
9. Baltic Sea
Unfortunately, swimming there is not very pleasant - it’s a bit dirty. Baltic fish is also not of the best quality. And it’s not even about the Russian attitude towards ecology. Our legislation is quite strict (sewage treatment plants in big cities can be compared with Europe, and often not in favor of the latter). The geographical position of the Baltic Sea is to blame: it is surrounded by industrialized countries (Norway, Sweden, the Baltic countries), oil tankers sail along it. In addition, due to the low temperature of the water, it slowly recovers its strength after contamination.
10. Black Sea
Despite its inherent romantic aura of “the bluest in the world,” it lags behind in our ranking. And it seems hopeless: it is physically impossible to restore it. The ratio of the catchment area to the area of the sea itself is the most unfavorable - 6:1, water exchange is very slow, and on top of everything else, the waters of the Danube flow here after traveling through three dozen European countries. At the Bulgarian resorts - Sunshine Bryag and Golden Sands - the sea is already completely brownish in color; last year the visibility was only 20 centimeters.
If you are going to swim in the Black Sea, it is better to go cold (up to 20-21 degrees): as soon as the water becomes warmer, the microflora (a possible carrier of infections) multiplies with triple enthusiasm.
Swimming in a dirty sea can cause not only skin irritation, but also infectious diseases of the ear and nasopharynx, and in rare cases, dysentery and even cholera. But most experts agree that the European Union and Greenpeace set fantastically high environmental standards for the purity of sea water. In theory, this severity is justified, but we have never heard of a person swimming in the sea and immediately developing red spots or contracting cholera. So if you find out that the sea off the coast where you are going to relax is not completely clean, you simply should not sit in the water for 10 hours a day. But with fresh fish, be really careful. All marine life accumulates toxic substances in higher concentrations than water.
Of course, in order to disrupt the ecological balance of the world's oceans and all its seas, you have to try hard, but humanity seems to be trying hard: now the pleasure of swimming in clean and clear sea water and eating clean seafood is a rare luxury. But for now it's allowed.
The waters of the Atlantic (66 m), Indian (50 m) and Pacific (62 m) oceans are considered the most transparent. The seas that make up them are distinguished by the natural purity of their waters. But human activity has an impact on the environment, polluting the once crystal clear waters with waste products. The situation is getting worse every year. The cleanest seas in the world may soon be included in the list of the dirtiest. So, a list of the 10 cleanest seas in the world.
1. Wedell Sea
The purest salt water is the Wedell Sea. The transparency of Wedella is 79 meters deep, which is significantly greater than that of other seas. Only distilled water is clearer than it. Its area is 2920 thousand square meters. meters, maximum depth - 6 thousand meters. In addition, Wedella is considered one of the coldest seas in the world. Almost all year round it is bound by Antarctic glaciers two meters thick. Winter water temperatures here reach -2 degrees. The sea was discovered in 1823 by the expedition of J. Wedell, after which it was named.
2. Dead Sea
The Dead Sea is not only the cleanest, but also the saltiest. Due to this, its “sterility” is ensured. It is located between Jordan and Israel. Its total area is 810 sq. m. kilometers. There is no marine fauna here. Even bacteria cannot exist here. It is impossible to drown in the waters of the Dead Sea due to its high density. Many tourists come here every year, as the dead waters have amazing healing properties.
3. Sargasso Sea
The uniqueness of this sea lies not only in its transparency, but also in the absence of clear boundaries without shores. The total area of occupied waters is about 7 million square meters. kilometers, 6 of which are covered with Sargassum algae (hence the name Sargassovo). Unlike the next representative of the rating, there is a fairly rich marine fauna here: various representatives of the fish family, sea turtles, crabs, etc. The water here is very warm and does not fall below +26 degrees in the winter season. The maximum recorded depth in Sargassovo is 7 thousand meters. The sea was discovered by Christopher Columbus, who referred to it as a “jar of seaweed.” Every year the environmental situation in these waters is deteriorating, which soon threatens severe pollution.
4. Red Sea
The waters of the Red Sea are not only one of the clearest, but also the saltiest and warmest. The average temperature is +30 degrees, and salinity in some places reaches 42%. This is the only sea on the planet that does not have freshwater tributaries. Its bottom is covered with corals, which give the sea the appropriate shade. The underwater world here is incomparably rich and beautiful, which attracts tourists here every year. Incredible coral reefs attract a huge number of fish here. Underwater here you can meet dolphins, green turtles and many other representatives of the living world. The most beautiful sea in the world is currently under serious threat of pollution due to discarded waste.
5. Cretan Sea
The Cretan Sea, part of the Mediterranean, is considered one of the cleanest. It is located between the Cyclades islands and the island of Crete. It also borders the Aegean Sea. North Crete is very popular among tourists due to the crystal clear waters of the coast and the amenities of beautiful sandy beaches. Many beaches on Crete have been awarded the European Blue Flag for the cleanliness of the sea.
6. Mediterranean Sea
The Mediterranean Sea is part of the Atlantic Ocean. The purity of the sea is considered relative. The clean zone mainly includes the coast of Greece, where the water is truly incredibly clear. As for the coasts of the same sea, which are adjacent to Spain and Italy, they are very polluted. Spain was fined for non-compliance with environmental standards, which did not stop the country from continuing to pollute Mediterranean waters. Despite this, the sea is distinguished by its species diversity of fauna. There are about 550 species of fish alone.
7. White Sea
The waters of the White Sea are considered the most transparent in Russia. It is part of the Arctic Ocean. Because of the curved coastline, the sea is also called the “Bay of Snakes.” The total occupied area of “white” waters is more than 90 thousand square meters. kilometers, and the maximum depth is 343 meters. The average water temperature here is quite low - +16 degrees, and in winter the temperature drops to -1.7 degrees below zero. For six months, the sea is bound by glaciers up to 1.5 meters thick.
8. Arabian Sea
The Arabian is in eighth place among the cleanest seas in the world. It is part of the Indian Ocean. The total occupied area is about 4 thousand square meters. kilometers, and the maximum depth is about 6 thousand meters. The clearest waters are found off the coast of the Maldives and the uninhabited island of Astola, which is one of the most popular ecotourism destinations. The waters of the Arabian Sea are very warm all year round: in summer the average temperature is +27, in winter it does not fall below +22 degrees. The Arabian was known to seafarers under several names: Omani, Persian, Green, Sindhu, etc.
9. Philippine Sea
The Philippine Sea is part of the Pacific Ocean. After Sargasso, this is the second largest sea on the planet with a total area of 5,726 thousand square meters. kilometers. Its uniqueness lies in the fact that the sea does not have clear land boundaries, just like Sargasso. It washes the coasts of the Japanese and Philippine islands, as well as the shores of the island of Taiwan. It has relatively low salinity. The Philippine Sea is rich in living fauna. Whales live here, which is why fishing and whaling are developed here.
10. Andaman Sea
The top ten cleanest seas that boast transparency are the Andaman Sea. It is part of the Indian Ocean and is located between the Malacca and Indochina peninsulas. The total occupied area is 605 thousand square meters. kilometers. According to some sources, it is known that the sea got its name in honor of the mythical god Anduman, who was revered in Malaysia. One of the richest underwater worlds is concentrated here, which has over 400 species of fish alone. Among the marine representatives living here, you can meet Irrawaddy dolphins, flying and reef fish, dugongs, sailfish, etc.
I'm lucky, I live by the sea and can swim or walk along the embankment every morning. At the same time, I see how the sea is polluted, every day neighbors throw garbage into the river that flows into the sea, thousands of tourists throw garbage on the beaches, bury cigarette butts in the sand and pebbles, not to mention the sewage system. Autumn and winter come, the sea gets rough, washes away all “traces of man” and throws them ashore; by summer, several trucks of garbage are removed from the beach. But this is only a third of all garbage and waste entering the sea and ocean, which remains on its surface, drifts in huge accumulations or is thrown back onto land. But the remaining 70% sinks to the bottom or remains dissolved in ocean water. TOP 10 dirtiest seas in the world - nature’s revenge for human irrationality.
1
The inland sea of the Atlantic Ocean - the Gulf of Mexico - is the leader of our parade of anti-purity. The main type of pollution is chemical. The rivers of Cuba, the USA and Mexico carry water poisoned by fertilizers into the Gulf, so the main pollution is nitrates and phosphorus. In addition, oil spills occur here with enviable regularity, and fish die from bacterial contamination.
2
The Black Sea may be more polluted than the Gulf of Mexico, but a serious environmental disaster has not yet occurred here. Although it is brewing. The drainage into the sea is six times its volume, and as you can imagine, rivers carry with them all kinds of pollution. And also hydrogen sulfide at the bottom...
3
The shocking truth about the Mediterranean Sea is that it is very dirty. Still love to bask in the sun on the shores of Italy and Cyprus? Choose a swimming place away from big cities. According to the latest report by the EU Environmental Group, 650 million tons of solid waste and 230 million tons of liquid pollution are dumped into the Mediterranean Sea every year, which includes lead, mercury, seafood, phosphates and so on.
4
The Baltic Sea is a real keg, only not a powder keg, but a chemical and nuclear keg. At its bottom are 500 thousand tons of chemical weapons in the form of bombs, containers and charges. There is evidence that some of them have already rusted, which is why mustard gas began to flow into the water. They say that nuclear waste is also flooded here, but this information is secret.
The fifth contender in our TOP 10 dirtiest seas in the world is the dirtiest sea in the Southern Hemisphere, and, alas, hopes for its recovery are almost lost. From time to time, sea water turns red - this is poisonous algae that multiplies in such quantities that it completely covers the sea horizon on popular beaches.
6
In some places, the very shallow Sea of Azov suffers from fish pestilence in hot years. In shallow waters, the water heats up so much that there is too little oxygen left for the healthy functioning of marine organisms. In addition, film oil pollution was found in its water area, which in area is equal to 0.05% of its surface.
7
The Laccadive Sea, which washes the coast of Western India, experiences all the “delights” of its proximity to its megacities. They do not stand on ceremony with the sea here: the concentration of heavy metals in its ports is 0.3-0.6 ml per liter, which is 3-6 times higher than the maximum permissible concentration.
8
Another hostage of maritime shipping routes, the Sea of Japan is heavily polluted with oil products, the amount of which exceeds the permissible concentrations by 10 times. In addition, pesticides and hydrocarbons from petroleum, DDT, are dissolved here.
9
The Caspian Sea, so to speak, is “suffocating” under the yoke of oil development. The content of hydrocarbons in its water has long exceeded the permissible concentrations; phenols in the water of the Caspian Sea are six times more than permitted.
10
The Red Sea is one of the warmest on Earth. This not only attracts tourists, but also leads to intense evaporation. The concentration of pollutants in sea waters is increasing every year. The pollution of this reservoir has led to the fact that the number of fish caught in it has decreased by 70%, and the number of tourists... tourists has only become more numerous.
