Oceans need oxygen
Updated: Dec 23, 2018
Oceans need oxygen and humans do too. Humans also need the oceans as a source of food, and as part of the water cycle, and as a producer of oxygen. Ocean plankton include plant like microorganisms and larger seaweeds and sea grasses which use CO2 and release oxygen. They help protect the atmosphere by removing much of the increasing levels of carbon dioxide (CO2) however the capacity of the oceans to continue removing CO2 depends on the life forms remaining in balance with each other. Increasing temperature and increasing acidity levels from dissolved CO2 that hasn't been used by the plankton or seaplants can make the ocean environment inhabitable for species that survive only within a certain temperature or acidity level.
The oceans have a problem - people.
Increasing amounts of nutrient rich run-off from agriculture or untreated sewage is leading to algae overgrowth, which then dies off when the nutrients are used up, and the dead algae cause an increase in growth of decomposition bacteria that use up the available oxygen - which then leaves no oxygen in the area for other fish or aquatic mammals such as dolphins and whales.
Imagine the oceans as giant fish tanks.
Fish tanks need oxygen, food, and waste removal:
air bubblers with tubing and a pump.
fish food added by humans
waste removal by humans cleaning the fish tank regularly or by including fish or snails that eat algae and other decomposing waste.
Life on Earth depends on ocean health - if we want to continue with business as usual, then we need to protect life in the oceans.
We need to start acting like the planet and ocean are our home - because it is - we are part of the fish in the larger fish tank of the whole planet. (To be continued - with an idea for aerating the oceans).
