Because there's no serious answers being given even though there are at least 2:
- trees have roots, roots ruin any nearby human infrastructure. You'll note this says "in urban environments" and that there are trees nearby, so this is probably the big reason
- trees need maintenance, which costs money. this is a stupid reason imo, but it's one nonetheless
- algae is cool, ok?
Algae is also more efficient per cubic meter, if I understand correctly.
Not just more efficient, vastly more efficient. Algae is 10-50 times faster at processing CO² than trees are. Some algae can be up to 400x as efficient.
It's just not as "nice" to look at, we usually associate algae with growth in unsafe bodies of water like bogs, etc. versus a nice clean pool or even a maintained pond.
On the other hand, algae do not produce shade, not sure if it filters atmospheric pollutants, and trees provide all sort of other services to the local ecosystem.
Maybe this invention can be used on places where trees cannot lives, but I'd still take a city with trees over a city full of green tanks.

Don't forget pollen and seeds.
Bees need pollen. We need bees and you can self host them.

Practical answer, fits in places trees may not. Pessimistic answer, fits in some guys cyberpunk ass vision for what he wants his office block to look like.
How do I self host these? I tried docker run liquidtrees it didn't work
They're not stupid; its not in docker. Check apt.
Try
docker run liquidtrees:micro-algae
I think there's an alpine build too if your system has low oxygen levels

git clone https://aur.archlinux.org/liquidtrees.git && cd liquidtrees && makepkg
or
add https://repo.30p87.de/private/archlinux as a repo, and sudo pacman -Sy liquidtrees. Then sudo systemctl enable --now liquidtrees

Nothing is wrong with trees, but the microalgae CO2 capture rate is 50x higher````` .
Their lifetime is also much shorter. Guess where all that CO2 goes, when they die ^^

I don’t think anything’s wrong with trees, but maybe we could also have some of these as well as trees ?
Replace the advertisements on bus stops with a really cool green liquid wall 😮 (but they’d have to make the glass super thick, these things tend to be vandalized from time to time)

First of all nobody is proposing to replace existing trees with that, that would be silly! AFAIU the people who created this also don't want these to be used where trees could be planted. They are outspokenly designed for already densely packed cities that are already highly polluted and hostile to trees, to start turning things around. Rebecca Watson's 6min take
Elon musk going into the tree business I see.
Trees grow and rip up the pavement around them. I do love the canopy though
Line the plater with steel, and this is not a problem. Bonus: trees are dwarfs and don't present risks of falling on structures in storms.

@ECEC Good lord the number of replies here from people whose brains have been destroyed by "planners"...
- Trees lower the urban heat island effect.
- There's plenty of room for trees in dense places, so long as "density" means efficient housing and efficient transportation rather than parking lots and stroads and single-family homes.
- Someone said "trees require maintenance", as if asphalt & pretty much everything doesn't require maintenance?
- Trees harm cars. But cars harm cars too!
Trees are also essential for insects, bird and animal life in cities. They are psychologically calming for people as well.

Is it FOSS?
Looks more like MOSS.

A big problem with trees is roots, especially in cities with dense underground infrastructure. If there’s an actual way to produce the same amount of oxygen as a tree in a smaller space, I’m all for it. I’m honestly okay with how these look, assuming low maintenance.
Very cyberpunk
