“Ocean deoxygenation: "Deoxygenated deeper ocean waters produce greenhouse gases such as nitrous oxide, carbon dioxide and methane that may reach the ocean surface and be released into the atmosphere, contributing to further warming" [Ocean deoxygenation - resource | IUCN

[ocean's account (phytoplankton) for 50% of earth's breathable atmospheric oxygen that we need to stay alive]


“Ocean deoxygenation”


“The oxygen content of the ocean has declined by around 2% since the middle of the 20th century overall, while the volume of ocean waters completely depleted of oxygen has quadrupled since the 1960s.


Ocean oxygen levels are expected to fall on average by 3–4% by 2100 overall due to climate change and increased nutrient discharges, though the scale of effect seen will vary regionally.


Consequences of ocean oxygen decline include decreased biodiversity, shifts in species distributions, displacement or reduction in fishery resources and expanding algal blooms.

Ocean deoxygenation threatens to disrupt the ocean’s food provisioning ecosystem services.


To slow and reverse the loss of oxygen, humans must urgently mitigate climate change globally and nutrient pollution locally.”

Was the earth made to preserve a few covetous, proud men to live at ease, and for them to bag and barn up the treasures of the earth from others, that these may beg or starve in a fruitful land; or was it made to preserve all her children?”
