Dead Zones in the Oceans, Seas, Lakes and Rivers

Dead zones are exactly that, deadly. They are oxygen-deprived or hypoxic bodies of water. Not much survives in these oceanic deserts as, not surprisingly, marine life needs a constant intake of oxygen to live. Large swaths of ocean habitats that would otherwise be teeming with life become biological wastelands.


Ecosystems Planetary Emergency – Warming Oceans

Planetary Emergency – Ocean Warming – The global ocean has warmed up more and more, year on year, in the last 50 years. Since 1993, the rate of ocean warming has more than doubled. Marine heatwaves have also doubled in frequency since 1982 and are getting hotter. We have polluted and changed the chemistry and temperature of the world’s oceans. This has caused severe stress to marine ecosystems and life.
