Researchers reconstructed the state of seawater as the ice sheets melted roughly 10,000-17,000 years ago, a period of climate change with parallels to our own, by using ocean sediment taken from locations between Chile and the Gulf of Alaska. The scientists found evidence of extreme oxygen loss all along the Pacific coast. More alarming, they found that it happened fast — in some cases, in less than 100 years.
Low-oxygen zones occur naturally in certain parts of the ocean, often some of the most productive for fisheries, as a side effect of nutrient-rich water coming to the surface. In Oregon, for instance, summer winds push warm, oxygen-rich surface water offshore, and cold, fertile, but oxygen-starved water cycles up from the deep to take its place.

Animal agriculture has the highest nitrogen and phosphorous footprint. We should shift to a plant-based diet, and then less nitrogen and phosphorous would be used, and this would help save our oceans, and ourselves in the process.

I dont thinks its global warming that causes this, but industrial and agricultural run-off.
