Dead Zones in the Baltic Sea

Dead Zones in the Baltic Sea Frankie M Abstract Dead zones, also known as hypoxia zones, are areas in the ocean where oxygen levels have been depleted or are depleting. Hypoxia could be due to natural reasoning, but more commonly it is a result of careless and uninformed inhabitants of the coast near that ocean. Farming, sewage, factories and fishing are all major causes of dead zones. If our corners continue to lose oxygen, we will eventually no longer have marine animals/marine life on our earth. This result will affect almost every aspect of our ever day necessities and lives.

Although this situation cannot be solved completely, it can sure be remedied. Keywords: hypoxia Dead zones in our earth’s corners and lakes should sound daunting as it is, but if not, think about never being able to go fishing, snorkeling, diving, whale watching or any of your favorite vacation excursions ever again. These hypoxia or “dead” zones are areas where human activities have depleted oxygen levels in the water. As a result, ten organisms Inundating tense places are letter laying or moving away. I en largest effected victim of this is the Baltic Sea in Northern Europe.

The excess nutrients we re polluting our seas with will soon be the reason we no longer see seafood in our grocery stores and restaurants any longer. There are ways to stop this quandary, but it will not stop without your help. Knowing the causes of this will help you to better understand the severity of saving Baltic Sea Dead zones. Hypoxia can be caused by a buildup of excess nutrients, like phosphorus and nitrogen, in the water, which usually comes from sewage and agricultural fertilizers. This kills off the organisms rather than feeds them. Because the World Wildlife Fund states that “coastal population of the Baltic

Sea is fifteen million” and increasing, it is safe to say that human activity plays a large role in causing dead zones. According to National Geographic, “Human activities have emitted nearly twice as much nitrogen and three times as much phosphorus as natural emissions. ” In the Baltic, not only are Cod fish dying from lack of oxygen in their water, but they are also being overfilled, which is a huge contributing factor to the problem. Cod fish help to keep algae levels low by eating sprat, which cause algae. Less or no cod nears an outbreak of algae and even less oxygen, which can be allied an algal bloom.

This will cause a spread in dead zones, be fatal to swimmers and animals, and turn away tourists. In many areas of Europe, the sewage system and waste from industries are not handled correctly. Often times the waste is dumped into lakes and the ocean causing pollution. As previously stated, many aspects of the lives of people living in northern Europe will be greatly affected if this problem is not dealt with. Fish and many marine animals’ lives will be put at high risk and if they do survive they will most likely be forced to move away and inhabit a more suitable part of the ocean.

This will create a chain effect and cause grocery stores to no longer be able to carry any or as much seafood products. The sea is becoming toxic, and hypoxia areas could potentially kill animals and humans and affect tourism revenue that the coastal areas depend upon. Dead zones will affect all features of life. Untreated algae levels will not decrease and will prevent any form of life from appearing there. There are ways to help prevent or remedy these tribulations. According to the World Wildlife Fund, “over 80 percent marine pollution comes from land based activities.

In the past, areas have decided to cut back on their pesticides and fertilizers as much as possible, but that solution is very difficult to keep up. The Finnish Environment Institute proposed another solution by enhancing filtration of the initial disposal of nutrients into waterways. Cutting back on fishing by limiting the amount able to be caught and/or giving restricted times to fish, could possibly help the population of cod to slowly be revived. Unfortunately, the causes of dead zones cannot entirely be blamed on human activity, or else the situation would be easier to solve. Daniel J.

Conley is a researcher at Lund University, who is working with the Swedish Agency for Marine and Water Management on a solution to the Baltic Sea dead zones. They have come up with an invention of a wind-turbine-driven pump that would reduce the amounts of phosphorus and nitrogen already in and going in to the ocean. As a geochemistry and a principal investigator of HYPER at Utrecht University, Caroline Sloop works with young scientists in discovering a solution as well. They have so far realized that the toxic ponderous In ten sealant AT ten sea moor Is Dealing released Into ten water.

Knowing this, they are working on figuring out how to extract that harmful nutrient out of the sediment. As of now there is not much I can do to help the situation other than inform my peers and others of the problem at hand. Although I may not necessarily live in northern Europe, the same problem follows all of us around the world. There are dead zones in places very close and accessible to us like, Monterey Bay, the Gulf of Mexico, and the Leghorn Slough. The dead zones near us may not be as severe but are Just as important and because they aren’t as brutal, we can catch he problem early and try to fix it.

Adjacent farmlands have caused fertilizer to runoff into the Leghorn Slough. With this information we can be more aware and take cautionary steps to preventing this as much as possible. Knowing that this situation is susceptible to any ocean or lake will hopefully encourage you to take this topic seriously. Ask yourself questions such as; could I survive without ever eating a single thing from the ocean? Could I go snorkeling in an ocean with nothing to look at but water and sand?
