Marine animals at risk as the ocean rapidly loses oxygen

The ocean is quickly losing oxygen, which could lead to the death of marine life in those waters.

A review published in Science Magazine details the causes, consequences and solutions, to what they call “deoxygenation.”

In the past 50 years the amount of water in the open ocean with zero oxygen has gone up fourfold and low oxygen sites in coastal waters have increased 10-fold, according to the study.

Scientists predict that it’s only going to get worse as the Earth warms up. However, scientists say the deoxygenation in coastal waters has nothing to do with human-induced climate change. Excess nutrients from agriculture and sewage cause excess algae growth. The algae then end up using too much oxygen.

Deoxygenation would force marine life to relocate or die off, meaning people who depend on fishing could lose their livelihoods.

Researchers say Fish kills in a single town in the Philippines cost over $10 million. Denise Breitburg, a marine ecologist with the Smithsonian Environmental Research Center, says the decline in ocean oxygen is one of the most serious effects of human activities on Earth’s Environment.
