I learned that dead zones are bodies of water with low oxygen, and because of that our aquatic life down there are dying or migrating to different parts. This is caused because the chemical bacteria runs off into the water and create the dead zones. I also learned that for over 50 years dead zone keep on increaseing there pollution caused by peoples pollution to our enviorment and the chemicals rush off into the sewer then the to a river or lake or till it its ay type of water bodies. These are the things that I have researched!!

Dead zones are a body of water that is completely abandoned by aqua life . The cause of this is that farmers use fertilizer to keep bugs away from their crops. Fertilizer contains dangerous chemical bacteria. The problem is that whenever it rains, the run off water takes the chemical bacteria with it. This water goes into lakes, oceans, bays, ect. These chemicals cause a substance called algae to forms in the water. Sea creatures need oxegyn to survive, but the algae takes all of it. Because of this, sea creatures die, or go in search of a different / safer parts. The amount of dead zones are increasing in size, by the year. People must take a thought about this and help to decrease the amount of dead zones............That is it!

Dead zones are a body of water with no life. The reason there is no life is because the oxygen is so low and the algae is just too much for the fish to handle. Another problem is the algae is not good for human skin so humans don't remove the algae and littl another problem is the algae is not good for human skin so humans don't remove the algae. Another thing is that when the algae comes deep in the water the clams and animals that live on the floor cannot escape. This is a problem because this aquatic life is dying because of something that humans created. We will find a way to limit the all dead zones but Intel then the best and we could do is not litter and take a care of the oceans .

Dead zones are awful because they are killing animal life because the dead algae are sucking up all the oxygen.

Dead zones are parts of the ocean that aquatic life can not live in or they have low oxygen. Dead zones are caused by chemicals and nutrients and chemicals like fertilizer from farms. the farmers put the chemicals on there plants but when it rains the chemicals runoff the land and into the ocean. the nutrients feeds algae that grow in the ocean. the plants eventually die and sink to the bottom of the ocean. The dead algae eats up the oxygen and the fish and other animals can not get the oxygen, so they either die or evacuate the area. this creates a dead zone because there is no life. this is a problem because animals such as fish are dying because of what we are doing. this affects us too because we eat fish but we if they are dying.
