Ocean anoxia
Extracted from the Wikipedia article Anoxic event.
Human activities in the Holocene epoch, such as the release of nutrients from farms and sewage, cause relatively small-scale dead zones around the world. British oceanologist and atmospheric scientistAndrew Watson says full-scale ocean anoxia would take "thousands of years to develop." The idea that modern climate change could lead to such an event is referred to as Kump's hypothesis.
