How do Dead Zones form? |
|
Nitrogen found in human pollution triggers blooms of microscopic algae known as phytoplankton. When these algal blooms occur, the masses of phytoplankton reach a point where they use up all the available resources in an area. When this happens, they begin to die. As they die, oxygen is absorbed out of the water as a part of the decomposition process.
The end result of this process is that the surrounding water is starved of oxygen and thus the marine life which breathes oxygen and lives in the area dies as well. |
