A field of seagrass converts carbon dioxide to oxygen at over 8x the rate of a forest the same size.

Underwater Meadows of Seagrass Could Be the Ideal Carbon Sinks

According to the UN’s Intergovernmental Panel on Climate Change, urgent and unprecedented changes are needed to avoid a climate change catastrophe. Although efforts are already being made to reduce the production of greenhouse gasses, they are by most estimations not enough.

It is therefore critical that we find ways to drastically reduce the amount of pollutants in the atmosphere. Ecosystems capable of absorbing and storing large amounts of carbon dioxide know as “carbon sinks” are ideal for this.

In principle, all living organisms – all animals, plants, algae and bacteria – consist of carbon and so function as a carbon sink. For example, as long as a tree lives it will absorb and store carbon. Given the sheer volume of all the tre… Continue Reading (3 minute read)

    Cyanobacteria (ocean algae) produces the majority of the oxygen in our atmosphere

    These bacteria sit at a certain depth in the ocean, low enough to avoid UV rays’ direct sunlight but close enough to the surface to utilize those rays for photosynthesis.

    Yet another reason our oceans are VERY important to protect.

    Phew, good thing we’re taking care of our oceans and not allowing companies to exploit them for profit. Thank god.

    I wonder if you could genetically engineer it to absorb even more CO2 and spread it everywhere you could.

    OK, let’s mow it down and put up a strip mall.

    So as the oceans rise and cover more of the earth’s surface, that means more seagrass fields, and eventually less carbon dioxide, bringing the sea back down? Just gotta wait a couple hundred millennia.

    Chop the trees and raise those sea levels! We bout to get oxygenated.

    Fix the oceans and you fix the climate

    I mean the benefit of forests over any other kind of carbon sink is that it’s useful. You can make shit out of forests, and with modern ways of treating lumber they can last centuries.

    Sounds like rising sea levels is part of Earth’s self-defense mechanism.

    Once the land became dry we had to retreat into the oceans. Those that weren’t destroyed by the storms or determined to self destruct in the dust knew what had to be. The only place we could survive was under the sea. The land had been used up, wrung out, and left turning to sun baked roiling heat blasted plains where only things that could hide, encrust themselves, or burrow might live.

    The only places we had left were the sea or the stars and for the majority the ocean was the only possibility. Some had left. Those who had resources and the will to build things just at the edge of what could be imagined. They had gone just as the fall had begun and it would be years until we heard back if they had found another place where Humanity might begin again.

    Now we fell into the sea like coming home after long being away. The sea, long abused and forgotten, welcomed us home. Now we farmed the sea like a new frontier. Excited, eager, hopeful every day we woke up and wanted to learn more, see more, build, do, make, and grow more than anything the thousands of years we had lived above had imagined.

    We had lost the world above until the stars spoke to us from distant worlds. In the time we still had the ocean, our ancient cradle, protector, and source of the very flesh we used to pass through our lives, embraced us and recalled us as its own.

    Once again we were at home and our green blue world spun sparkling in space while it’s children dreamt deep in the warm waters of the world they had lost and of the worlds they might build if a second chance could be possible in the endlessly forgiving world that had given them life.

    Time for some seagrass farms.

    Is it because the animas in the ocean use less of the oxygen? I heard Chris Hadfield say that not one breath of oxygen leaves the Amazon because of all the animals there.

    Yeah, but then the air smells all fishy.
