Explanation:
Dead zones in seas and oceans are mainly caused by eutrophication, which is an excess of nutrients entering the water through human activities, leading to low-oxygen conditions where most marine life cannot survive.
The major cause of 'dead zones' in seas and oceans is primarily due to eutrophication, which is characterized by an excessive amount of nutrients, usually nitrogen and phosphorus, entering the water bodies. These nutrients primarily come from human activities, such as agricultural runoff, waste treatment plants, and fossil fuel emissions.
When these excess nutrients are available in the water, it leads to a rapid increase in the growth of algae in a process called algal bloom. When these algae die, they are broken down by bacteria through a process called decomposition. This decomposition process requires oxygen, leading to a significant decrease in the amount of dissolved oxygen available in the water. This creates a low-oxygen condition known as hypoxia. When the oxygen levels become exceedingly low, it results in dead zones where most marine life cannot survive.
