The purpose of this research paper is to make more people aware of ocean dead zones and how they can not only affect the marine oasis, but how the can affect us as humans also.
Dead zones are a more common term for the word hypoxia, which means lower or reduced levels in the water. Dead zones are areas in oceans and lakes where the oxygen levels are low, too low for most organisms to survive in them. Dead zones are so because of a process called eutrophication. Eutrophication happens when a body of water gets too many nutrients such as phosphorus and nitrogen. These nutrients are fundamental in the growth of a group of single-celled organisms called cyanobacteria, or blue-green algae. When the nutrients in the water are at a normal level, cyanobacteria are normally produced. When the water is overloaded with those same nutrients, however, it can be very harmful. Human interaction is the main reason why these nutrients are being washed up into the oceans. Therefore, dead zones are primarily located near inhabited coastlines. These nutrients end up in our air, water, and soil. Humans and their daily activities emit twice as much nitrogen and three times as much phosphorus as natural emissions. Eutrophication also depends on the region you are in. Developed countries excessively use cow manure and other commercial fertilizers, which are the main causes of eutrophication there. The runoff from farms and agricultural sites enter creeks and bays due to rain or irrigation, in
