Global warming and agricultural pollution have drastically reduced oxygen levels in the ocean over the last 70 years.

Coastal dead zones with zero oxygen have quadrupled in size since 1950, while the number of very low oxygen sites have multiplied tenfold, a new study published in the journal Science finds.
