Area of global dead zones doubling every 10 years

The number and size of oceanic dead zones is increasing.

The name says it all, but dead zones are areas along the sea floor where oxygen levels are so low they no longer sustain marine life. Hypoxia, which is a deficiency in the amount of oxygen reaching the tissues of organisms, is a widespread and growing problem in Earth’s oceans as industrial waste, fertilizer runoff from industrial agriculture and anthropogenic climate disruption increasingly aggravate the crisis.
