Marie Nordströ​m, a member of the ICES Workshop to Review the Marine Strategy Framework Directive Descriptor 4, explains hypoxia.

'Hypoxia essentially means 'low oxygen'. Aquatic animals need oxygen to breathe, just like terrestrial ones. When seawater contains very low levels of oxygen there are detrimental effects on fishes as well as other animals living on the seafloor.

Hypoxia alters species physiology and behaviour, and eventually, mobile animals flee the hostile conditions, but the rest die, leaving only bacteria capable of thriving in low-oxygen environments. Whereas some areas experience natural hypoxia, human activities exacerbate the occurrence, frequency and severity of hypoxic events by over-enrichment of nutrients in coastal waters throughout the world.

In my work on food webs, I study the links between species – who feeds on whom – and the importance of these interactions for maintaining a functioning ecological community. Hypoxia affects interactions between species, as well as the structure and functioning of entire communities.'​

Low oxygen truly affects the environment of species including themselves. It's good that researches about this matter are present to inform us more about it.

Wow, quite interesting. So is there certain activities that humans can do in order to see an increase in oxygen in the water? Daniel | https://www.treeservicebrandonmb.com/tree-removal-brandon-mb

It is the impact of man that is causing increase in hypoxia at alarming levels, not only in the aquatic environments but also on land. I recently wrote a research article for https://studentmindset.com/ on these harsh impacts and what they mean for the future of life on this planet.

MarieNordström did good research,hypoxia is a new topic of human, the rearch result can explain some problem happend to human but the reson no one knew, but I am curious how hypoxia can happen?
