Isn’t spirulina more effective for capturing carbon than trees? And also you can eat it in the way you don’t normally eat trees? Trees are great and all but why do you want me to be angry about algae?

I had the same reaction until I read this.
TL;DR: it’s 10-50x more efficient at cleaning the air and actually generates both electricity and fertiliser.
Yes, it would be better to just get rid of all the cars generating the pollution in the first place and putting in some more trees, but there are clear advantages to this.

It provides fertilizer but needs “some food”.

rumba@lemmy.zip 6 hours ago
It’s just some circle of life stuff, fertilizer, carbon dioxide, light in, The algae produces more algae. It loads up on a bunch of carbon, some of the bloom dies off, by removing it, you take the carbon with it along with some of the fertilizer components. You add a little more fertilizer in and the algae blooms more and sucks up more carbon dioxide.

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?
pennomi@lemmy.world 1 day ago
Algae is also more efficient per cubic meter, if I understand correctly.
halcyoncmdr@lemmy.world 23 hours ago
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.
Dremor@lemmy.world 1 day ago
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.

I think you mean all, as this reads more like “nuh uh, trees don’t ruin anything”
But smarter urbanism is possible and in fact does exist.
And those are not the norm, so for places that don’t plan to just destroy what’s already there and start anew, this is an option

Wrong community, maybe? Lol

iirc, algae are better oxygen producers per units of mass and volume, so a tank full of algae might actually be better than a tree. One issue though is that trees can grow on open ground, while algae require a tank to be built, most likely negating the economic benefits. Also, trees are more aesthetically pleasing.

Capricorn_Geriatric@lemmy.world 19 hours ago
Short answer: the bank won’t give your shiny new tree-planting business a loan as easily as it will to a “liquid tank tree replacement” one.
Long answer:
- Trees take time to grow
- Trees need to be planted
- Trees make shade
- Animals like birds and insects like bees and mosquitos like to live next to them
- Trees don’t need electricity
- Trees take in heat radiated from the pavement
- Trees don’t look cool
While algae are more efficient at turning CO2 into oxygen in theory, in practice algae don’t have a good climate in such a tank (no oxygen without ventilation, i.e. constant electricity and they get cooked through the glass).
All in all, more of a gimmick than anything.

Roots limit where they can grow without messing up infrastructure.
Dozzi92@lemmy.world 7 hours ago
Yeah this is a big problem I see often. You have underground utilities? Tree planting becomes a huge thing. And in a lot of these walkable areas, places you’d want trees, folks tend to also prefer not to have the wires overhead with telephone poles everywhere, and so they’ve been backed into a corner.
I did just sit through a presentation by my local environmental commission where they addressed the issue. The solution seems to be trees bred for the specific environment: deciduous provides shade but doesn’t drop a lot of leaves; can grow tall but the root ball grows in a certain way so as not to interrupt sidewalks and utilities; hearty and resilient. I can’t recall the trees, but they were described as essentially not naturally occuring.
CheeseNoodle@lemmy.world 19 hours ago
Aren’t like half of those bullet points positives? Also in addition to what you said once you got a tree you got a tree, those tanks need constant maintenence and cycling which I doubt anyone is going to bother with for more than a year after installing them.
Rakonat@lemmy.world 18 hours ago
The comment you replying to was trying to not so subtly point out this is a business plot and little else. Nobody is going to pay a subscription fee to have a tree in front of their business, but they might cough up money for a third party to maintain a tank of algae out front if it was sold right
ArcaneSlime@lemmy.dbzer0.com 16 hours ago
- Trees take time to grow
Sure, of course not removing literally all of them in the first place is preferable but hindsight is 20/20 I guess. And good things come to those who wait.
- Trees need to be planted
True, planting a tree seems a bit easier than installing a weird tank though, despite time to grow.
- Trees make shad
Good.
- Animals like birds and insects like bees and mosquitos like to live next to them

I think it’s probably cheaper in the long run to self host a tree instead, unless you live in an apartment with absolutely no green space. But I’d rather get a VPF and host a tree there if I had too
hazl@lemmy.blahaj.zone 5 hours ago
Problem with VPFs is irrigation throttling, or lack thereof. Most people are cool, but I’ve heard of people hosting exotics which just max out downstream 24/7. Plus everyone has root access which gets abused frequently.

I’m gonna bet that you’re going to get a much-more-economical return there by powdering whatever iron is used in building that thing and then dumping said iron powder into the ocean at an appropriate point.
jagged_circle@feddit.nl 15 hours ago
This technique is controversial because there is limited understanding of its complete effects on the marine ecosystem,[5] including side effects and possibly large deviations from expected behavior. Such effects potentially include release of nitrogen oxides,[6] and disruption of the ocean’s nutrient balance.[1] Controversy remains over the effectiveness of atmospheric CO2 sequestration and ecological effects.
Geoengineering is bullshit proposed by funding from fossil fuel companies so they can continue to pollute.
The solution is simple: make it illegal to pollute. Fine the companies responsible for their contributions to the climate catastrophe out of existence.

@ECEC Good lord the number of replies here from people whose brains have been destroyed by "planners"...
1) Trees lower the urban heat island effect.
2) 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.
3) Someone said "trees require maintenance", as if asphalt and pretty much everything else requires maintenance.
4) Trees harm cars. But cars harm cars too!mosiacmango@lemm.ee 1 day ago

Dendrocnide moroides, commonly known in Australia as the stinging tree, stinging bush, or gympie-gympie, is a plant in the nettle family Urticaceae found in rainforest areas of Malesia and Australia.[3] It is notorious for its extremely painful and long-lasting sting.

A big problem with trees is roots, especially in cities. 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.

It’s exponentially growing and if you don’t wanna eat it, it makes great organic fertiliser or animal feed with lots of protein and micronutients!

Any city manager could tell you everything wrong with having trees downtown.
* Birds get into them and when they're nesting, they attack anybody walking by
*Birds also shit on the cars parked under them, and most drivers look for shade to park under
*Bugs get into them and attract birds when birds aren't nesting
*Trees drop sap, which also ruins a car's finish
*city workers have to spend time on the clock keeping the leaves picked up off the groundYeah, the drawback is that the algae don't provide shade.
