The sea is like the bloodstream of the earth's body. Just as humans do not survive when their blood is polluted, so the earth does not survive when its oceans are polluted. This sea is being polluted today. Behind which 80% of the people are responsible. Every year on the 6th of June I make this mistake and try to clear it up a bit. I started sea pollution again before 9th June. Nowadays the spread of sea pollution is so far that if you don't throw a polythene on the beach, the headline could be using something perishable instead of polythene! I almost met them in Dadagiri. But many do not know how they are polluting the sea!
A little history: Despite a long history of marine pollution, significant international laws to combat it have not been implemented until the twentieth century. Marine pollution was a concern during multiple UN conventions on maritime law, beginning in the 1950s. Most scientists believed that the oceans were so vast that they had an unlimited ability to thin and thus be free from pollution. In the late 1950s and early 1960s, there were several controversies over the recycling of radioactive waste by the Atomic Energy Commission from British recycling facilities at Windscale and the dumping of radioactive waste into the Irish Sea off the coast of the United States through the Mediterranean. By Atomic. In the aftermath of the Mediterranean controversy, for example, Jack Castiu became a global figure in the campaign to end marine pollution. Marine pollution made further international headlines after the accident of the oil tanker Torre Canyon in 1986 and the Santa Barbara oil spill off the coast of California in 1989. Marine pollution was a major topic of discussion during the 1972 United Nations Conference on the Human Environment in Stockholm. That year also saw the signing of the Convention on Temporary Pollution Prevention, sometimes known as the London Convention on Dumping of Waste and other issues. The London Convention did not prohibit marine pollution, but did create regular black and gray lists by national sanctions (black) or regulated by national authorities (gray). Cyanide and high-level radioactive wastes, for example, were blacklisted. The London Convention was applied only to the application of waste discharged from ships and thus did nothing to control the waste discharged as liquid from the pipeline.
Let's start with what the sea thing is. The oceans are the interconnected waters of saline water, which cover more than two-thirds of the earth's surface. The sea separates the continents geographically. And the seas have partially surrounded the sea. Then comes the beach. A beach is a type of geological terrain that forms on the side of a body of water. But the land formed by the side of a lake or haor type reservoir is not considered as a beach. This only applies to land around the sea. It is usually made of loose material, such as rock, pebbles, sand, gravel, etc. And all this is part of the sea.
Let's sing a little before. Seawater has the highest amount of sodium chloride (NaCl) so it tastes salty. We get edible salt from here. The water needed to keep the earth's climate tolerant also comes from here. The water cycle, the carbon cycle, the nitrogen cycle play the biggest role in running smoothly. Always maintaining the balance of the environment.
Different types of bacteria, protists, algae, plants, fungi and animals are found in the sea. For this, a diverse marine habitat and ecosystem has developed in the sea. These habitats and ecosystems range from the sunlit waters and shores of the ocean surface to the deep, high-pressure seas of the cool and dark seabed, and from the cool waters of the Arctic ice sheet to the tropics along the axis. Several major groups of plants and animals have evolved at sea. The origin of life probably happened at sea.
The sea provides plenty of food for mankind. Fish is the main one. However, shellfish, mammals and seaweed are found in the sea. These are either caught by fishermen by throwing nets or cultivated under water. People also use the sea for leisure activities such as trade, tourism, mineral extraction, power generation, war and swimming, leisure travel and scuba diving. I use this sea for many, many more purposes. Now let's come to the real issue of pollution.
1. Believe it or not, most of the pollutants in the sea come from plastic waste. Of the 260 million tons (!) Of plastic per year, more than 10% is disposed of at sea. It must be believed that plastic is a threat, a name of destruction. Plastics released into the sea take a long time to decompose. According to a United Nations study, between five million and one and a half million tons of plastic waste enters the sea each year. A large part of it goes to the bodies of fish and seabirds. Plastic has even been found on the bodies of animals at the bottom of the ocean. According to the Environmental Protection Agency (IUCN), car tires and small plastic wastes from various textile factories are the main causes of marine pollution in different parts of the world. About 30 percent of the total pollution is caused by plastics. However, half of the oxygen we receive is produced by seaweed and phytoplankton. The oceans absorb carbon dioxide at a rate fifty times higher than our atmosphere and reduce climate change.
I know something, but reducing the use of plastic is not so easy. Because of its availability and low price. Dipu Sarkar's brother's little sci-fi:
This discovery by the scientist Calculus is going to make all the resources of the sea suitable for human use. Thousands of tons of gold, silver, salt, sulfur, silicon, lithium ... all that is useful to man will be rescued from this sea. But the same! I see tons and tons of plastic is only available from this device.

2. Then comes sewers and industrial chemicals. Most of them come to the Nardmai river in their Ititan. Then first the river is polluted and the garbage is dumped in the sewers. Then the river also came to an end in the sea. Whatever happens, the garbage comes and mixes in the sea. Just what the hell! There are many chemicals.
Chemicals cause many changes in the marine ecosystem. Oxygen levels in marine ecosystems are declining, plant life is declining, and seawater quality is declining drastically. As a result, ocean life, all levels of plants and animals are highly affected. Many times this chemical also reaches the bodies of animals. Survival becomes difficult. Survival is a change in life!
Moreover, this toxic chemical raises the temperature of the sea. This is a phenomenon known as thermal pollution. This is because the temperature of these liquids is quite high. Animals and plants that cannot survive high temperatures.
3. Land runoff is another good (negative) source of marine pollution. Land runoff is the flow of water when excess rain water, storm water, molten water or other sources cannot enter the soil in sufficient quantity. As a result, the water flows into the canal or river. Many canals are again connected to the river or canals are built near the river. As a result, somehow it went to the river.
Often, these waters contain man-made harmful pollutants that pollute the oceans. It washes away the soil. Construction of roads, buildings, ports, channels and shelters can carry soils and particles containing carbon, nitrogen, phosphorus and minerals. This water can enrich algae and phytoplankton in coastal areas (called algal blooms) which have the potential to create hypoxic conditions using all available oxygen. Harmful algal flowers have been found off the southwest Florida coast for more than 100 years. These algal flowers cause the death of species of fish, turtles, dolphins and shrimp, and have a detrimental effect on people swimming in water.
Climate pollution from roads and highways can be a significant source of water pollution in coastal areas. About 75% of the toxic chemicals flowing in Puget Sound carry stormwater that blocks paved roads and driveways, roofs, yards, and other developed lands. California has plenty of rainstorms that flow into the ocean. These rains occur from October to March and the water that flows contains petroleum, heavy metals, pollutants from emissions, and so on. Fertilizers and wastes from land animals and humans can be hugely harmful to the oceans by creating a Dead Zone.
4. Then there is the pollution caused by ships. It happens in many ways. But the most devastating can be oil spills that are toxic to marine life. The polycyclic aromatic hydrocarbons (PAHs) found in crude oil are very difficult to clean and last year after year in the marine environment.
In many cases ships dump illegal waste into the sea despite foreign and domestic regulations prohibiting such measures. There are some places; Dirt is not allowed to be dumped where there is a fine, they are encouraged to go a little further and dump garbage in that sea again. 🐸 In addition, ship travel, garbage, etc. affect the ecology of the sea.
5. Ending with a natural contaminant like today. Our air flow! It is not enough to just leave the garbage in a certain place due to the flow of air. Air-blown dust and debris, including plastic bags, have flown into the sea from land and other areas. As the epicenter moves north through the colonial Atlantic during the warmer seasons, dust from the Sahara, which revolves around the southern periphery of the highlands, moves to the Caribbean and Florida. The dust can also be attributed to global transport from Kobe, Japan and the Gobi and Takalmakan deserts across the North Pacific to the Hawaiian Islands.
There are many more ways to pollute the sea. However, in my opinion, these are the main ones and it is possible to highlight a lot in their descriptions, but I do not have the patience to write so much.
However, despite all this, the sea has survived fairly well. But that can't last long. If this continues, there may be a sea, but nothing will survive in the sea. There will be no diversity in the depths of the sea. You know what would have happened. So release the sea of prayer to everyone. Try to prevent pollution. Save the sea, save the earth.
