Ballast Water Destroying The Ocean
Man has no right to enjoy the ocean alone. All living beings have the same right as the ocean. A relationship with the sea is associated with all animals in the evolutionary process. Man benefits from the sea.
Humans use the oceans for protein-rich foods, transportation, electricity, various pharmaceuticals, entertainment, and many other uses.
What is this ballast water that destroys the ocean?
A significant number of ships worldwide ply the seas daily to transport passengers and cargo. So different oceans have different depths and Difference pressures. Ballast water is the water used to maintain the balance of a ship. They have their way of navigating Difference shipping lanes.
Most ships load or unload ballast water in proportion to the weight of the item. During loading and unloading.
Before 1880, the solid material was used for ballast in ships. Stones and sand were used for this purpose. This required human labor to load and unload the ballast. So this was a difficult task, as well as a risky one. If the ballast is not released correctly, there is a possibility that the ship will break its balance and sink. So this was a big problem during high tide. Later, with the advent of shipbuilding, Began to use water for ballasts. With the ease of pumping and discharging water into the tanks and the absence of human labor, this task became more convenient and efficient.
Why do ship ballasts use water?
The ships are Created to transport large quantities of goods, oil, and people. These vessels use a large amount of ballast water.
Damage caused by ballast water
Ballast water causes environmental damage by transferring this water from one ecosystem to another. Aliens that enter ecosystems have problems living in those ecosystems.
01. Affects the food chain of living organisms in the ecosystem.
02.Can destroy the breed.
03. Addition of predators to ecosystem organisms.
04. Organisms in that ecosystem can lose habitat.
05. The ability of new organisms to become parasites.
06. Toxins can accumulate in the environment.
Alien marine life can be harmful to fishing nets and gear. There is also the potential for new diseases to spread. So this could disrupt the fishing industry.
If the disease spreads, the fish that live in the ecosystem can also be infected. It can also spread the disease to people who eat fish.
Methods used to destroy ballast water organisms.
Several steps can take to begin the process To control the environmental impact of ballast water.
01. Ballast water filtration.
02. Purification of ballast water by chemical method.
03. Heat treatment.
04.Oxygenation of water
06. Destroying foreign organisms by sending electric currents on the water and releasing the water.
07. Radiation therapy
Further on ballast water
Estimated worldwide – 11 to 16 billion metric tons of ballast water has been using annually today. More than 3,000 alien organisms migrate to various ecosystems daily with this ballast water. These organisms pose a majority obstacle to sustainability in ecosystems.
The first revelation about ballast water
The first revelation of ballast water by scholars was made a hundred years ago, in 1903. Odontella, a group of algae living in the Asian seas, has become widespread in the North Sea. New research on this subject in detail has been going on since the 1970s. In the 1980s, Canada and Australia faced several crises due to this invasive algae.
So this is further accelerated Because international trade and transportation are booming.
Ballast identifies several species of invasive organisms circulating in the water.
Endemic to the North and South American seas, ballast waters have affected the Black Sea, the Caspian Sea, and the Sea of Azov. There is a rapid spread.
These organisms disrupt the food web and the environment. In the 1990s, the Black Sea and Azov seas suffered major setbacks. As a result, the fishing industry collapsed.
It is widespread in the Gulf of Mexico and the South American seas. In 1991, an epidemic swept across South America from three parts of Peru
Restricted to the Baltic Sea, the Black Sea, and the Caspian Sea, the creature caused damage to fishing nets and harmed the economy.
Migrated from Australia to the Pacific. This highly contagious organism feeds on oysters of commercial value.
Although endemic to the Black Sea, ballast formed in the Baltic Sea of Ireland and the eastern seaboard of North America. It was a threat to food chains and endemic animals.
Although endemic to North Asia, it has migrated to Western Europe, the Baltic Sea, and western parts of North America. The diversion of river banks caused soil erosion. Eats endemic fish.
Endemic to the Azov Sea and the Caspian Sea, the organism spread to North America and the Baltic Sea by ballast water. This fish is very aggressive and can adapt to any situation. This animal is at risk of losing the habitat of other marine life endemic to those areas. Small fish and fish eggs of commercial value are the food of this animal.
This species migrated to the African seas and the United States and inhabited the coastal areas of Europe some time ago. Habitats are uprooted by fighting with endemic species.
Although many environmental problems have arisen due to ballast water, no 100% successful solution has yet been found. So this is a matter of concern not only to marine life but also to humans.
So this is the second article I’ve posted on this web page about the ocean. I will leave the link to the previous article below. We will talk about more important topics related to the sea in the future. If you want to know more about the ocean or any other scientific facts or issues, add comments in the comment section.
