Oxygen is toxic anyways. Every organisms that breath or has breath oxygen is dead or will die one day.
Algea produces way more usable oxygen than trees. Trees consume most of the oxygen they produce.

Damn straight.
Trees don't actually produce a lot of oxygen, at least not in aggregate. That's because for every ton of biomass the worlds forests gain through trees growing, you get an equal or larger amount of biomass disappearing through rotting or burning, which... releases CO2 and consumes O2. Only if tree cover as a whole grows can trees in aggregate actually increase atmospheric oxygen and decrease atmospheric CO2.
Unfortunately, that hasn't happened in centuries, maybe millenia if you discard some minor short-lived recovery periods after major reductions in human population after, for example, Gengis Khan's conquests in the 13th century, the black plague in Europe in the 14th century or the extinction 90+% of North America's native population by Eurasian diseases in the 16th century.
iirc when algae die, chances are they sink down to the bottom of the ocean, where they (and their captured CO2) will stay for the next million or so years.
So start tying up bundles of dead trees and sink them?

Seriously though, that would be an easy solution for hemp roots, and hemp captures 10 times the amount of carbon in one harvest, the thing is that you can harvest hemp 4 times a year in many places, and 80% of the carbon is stored in the roots. If we compressed the roots and dumped them to the bottom of the Marianas Trench, that might be a viable solution that we could get funded. You can make a shit ton of stuff out of the plant (including both food and biofuel) and only release back 20% of the carbon.
That's a very interesting idea.
Quick question, you say 80% of the carbon is stored in the root and that you can harvest hemp 4 times a year. Do you harvest the roots when you harvest it? Or are you only harvesting 20% of the total captured carbon on each harvest?
Yeah, harvest the roots so that you dump that 80% in a compactor. Once you have a cube that won't float, and is a couple tons of carbon, dump it in the ocean.
Just don't use the roots or let them rot above sealevel.
The best idea I've heard is to grow fast growing plants then burn them to make power while you capture the carbon using a portion of the power generated - the carbon is either mineralised into building materials or dumped in the old coal mines where the carbon originally came from.
It's a great way of dealing with excess biomas from managed spaces like coppiced city trees, the same can work with algee either cleared from waterways or grown purposeful in polluted water where it'll help extract various toxic elements.
We really have made so many amazing advanced in tech the can help balance the atmosphere but there's so much negativity from both sides they don't get anywhere near the attention they should.
Not if it is in a puddle.
That's not entirely true. Yes, trees lose most of the Carbon they fix when they die, but a part goes into the soil and can remain there for hundreds of years. Also, the type of forest matters - as a forest matures, or if you let a monoculture plantation rewild into a forest, it will be able to suck CO2 even without increasing in area.
As far as I know forest cover in most of Europe is higher than it's been in over 100 years?
I’m gonna hold my breath and live forever.
wont help you, you already inhaled oxygen
Oxygen is actually pretty toxic. At atmospheric pressure, it has to be diluted with nitrogen to not kill everything
Found the anaerobic bacteria trolling as a human. Get outta here!
Oxygen being toxic is literally a JoJo reference
I thought they made more than trees?
Yes, the number i found is around 80% of oxygen production worldwide.
Thank for confirming
Sphagnum moss for peat bogs be left out of the carbon capture conversation too. They just want love.
I've recently developed a mild intolerance to Carageenan, and it's making me acutely aware of just how amazing algea is.
It's in everything and can do anything, truly an amazing organism.
But I wish it wasn't so great at everything, because I want to brush my teeth without randomly throwing up 2 hours later because I'm allergic to toothpaste.
I don't think it's in the Sensodyne families.
Source: I have personally manufactured it.
That's a really healthy attitude
Everyone is actually mildly intolerant to carageenan. Why it's used as a food additive is beyond me.
Edit: My wife switched us to Colgate and hasn't had problems since.
F in the chat for victims of the Great Oxygenation Event.
The anaerobics got what they deserved! Hail Oxygen!
Algae are also the preferable bioenergy source compared with using trees.
Algaes should never be sad. If you come across a sad algae making sad algae noises, please give it a soft kiss and word of encouragement.
I grow algae for carbon capture as a hobby.

I'm dumb. What does this n degree number thing mean?
OP is almost certainly recreating the Latin Numero sign, №, used in cases like e.g.
№ 6
It's often stylized with the degree sign, °, or with the superscript 'o' underlined.
You can type it on phones by long pressing the # key
like the other guy said N° means number. now why he overcomplicated so much? dunno.
It is shorthand for "number". N°6 is read as "Number Six".
I'm not a number, I'm a free man!

WTF is that description
Nah they're cool
Not only that, everyone who has ever had cancer has had exposure to oxygen. That said, dihydrogenmonoxide is another common chemical that everyone who's died has had exposure to...
