While I don’t want to spoil the joke (but I will) and I hate techno-optimist solutions that displace actual solutions for our biosphere: supposedly, Belgrade is such a dense concrete hell that trees aren’t viable solution (at least in the short term).
There is some rumbling that liquid trees are not the solution to the real problems caused by large-scale deforestation, nor does it reduce erosion or enrich the soil. However, much of this wrath is misplaced as Liquid tree designers say that it was not made as a replacement for trees but was designed to work in areas where growing trees would be non-viable. Initiatives like Trillion Trees are laudable, but there is something to be said for the true utility of this tiny bioreactor. The fact that they can capture useful amounts of carbon dioxide from day one is another benefit for them. Such bioreactors are expected to become widespread in urban areas around the world as the planet battles rising carbon levels in the atmosphere.
And for people who think that the trillion tree idea is anything else than just the oil lobby running with a feel good solution, I have a great podcast episode for you
Spotify doesn’t work on my phone. Care to link the podcast page on a platform not trying to corner the market, please?
I listen to it on apple podcasts if that helps
How, if I can’t find out which podcast it is?
You can click the spotify link and it literally tells you what it is
I already said thatspotify doesn’t work on my phone (the homepage crashes)
It’s an episode of “The Climate Denier’s Playbook” entitled “Let’s Just Plant a Trillion Trees.”
They seem to be focusing on CO2. Trees in cities are going to capture a negligible amount of CO2 and for relatively high cost versus doing things outside a city. The point of trees in cities is shade and looking nice (good for mental health). Liquid trees solve neither of those.
And ameliorating the heat island effect.
But mainly quality of life.
Also, trees are surprisingly difficult to keep alive if they were artificially introduced to a location. Turns out they don’t thrive in a concrete hellscape super well.
Which is why native species are always recommended
There are places with no native trees. A majority of the earth’s land area is naturally treeless.
They can thrive in tap water and can withstand temperature extremes.
So maybe they can be used in regions that are too hot for trees, like desert cities
If it’s actually more efficient then trees, could be a good idea. Saw a 51/49 video where he explained the urban development in the US requiring only male trees be planted leads to increased pollen levels and has made the “allergy season” 30+ days longer over the past 50 years or so.
I still want the trees outdoors, but this would be cool for indoor spaces. Each mall or parking lot could have a solar panel overhead and slime-tanks to produce useful byproducts.
Maybe it could be mixed with and aquaculture like fish and sea plants to create cool scenery
While I would hate to lose actual trees, I’m medium on the idea of this on it’s own. People need lots of things and space, which causes the removal of trees. If we can replicate some of their functions, such as CO2 absorption with this tech, then that seems good. If upkeep is the same as a tree, I don’t see a downside to the overall concept.
My thought would be that this shows up on top of the buildings instead of at ground level, though… Plant real trees and put these on the roof. The real loss would be if we stop making green spaces because these things meet the need for O2. Green spaces in cities do way more than just clean the air, though, so I’m not sure we’re that dystopian yet.
The photo looks like it doubles as a bench too, so maybe that helps justify its footprint. Make them a mini-light show with varied colors and it can become a functional art installation. How long until it has spikes to prevent someone from taking a nap on it, though?
Yeah completely agree, I like trees and don’t want them completely gone or anything.
I discovered when I joined a volunteer litter-picking group in my town that some people really hate trees. And I must emphasise HATE. They hate the shade they cast in summer, the way the leaves block the all-important View. They hate the fallen leaves in autumn. They hate the bare branches in winter. They hate the risk of branches falling in storms. They hate the racket the birds make. I was astonished - it never occurred to me that people would feel so strongly.
Turns out I’m a bloody tree-hugging extremist.
That’s just unhinged. The trees are the view.
Those “people” would better serve as fertilizer (specifically for trees)
I guess I’m too…born and raised in a forest?..to be the same species as those people.
Leaves are annoying in urban areas with full concrete/asphalt/metal/glass environments. Different people like different things and some aesthetics are incompatible.
Yeah trees are assholes. They always ring my doorbell trying to sell me the book of Gaia. Constantly telling me “you can’t smoke here, sir”. There’s a tree behind my house who constantly wears the same glasses as me. Whenever I buy new ones, a day later this tree has the same. He’s constantly mocking me for no reason.
I think all trees should be cut down and burned. Algae never complain, are always kind and always say “good day sir” when you walk by.
A tree stole my wallet and had sex with my wife!
So many trees have destroyed people their houses with stupid forest fires. Have you ever heard of algae fires? No! Because algae aren’t assholes!
let me introduce you to this: https://www.scientificamerican.com/article/robo-bees-could-aid-insects-with-pollination-duties/
humans are crazy. You want to know whats wrong with trees and bees? It’s pretty hard to make a profit of them
All these braindead silicon valley tech bros trynna reinvent existing solutions to problems in very expensive and unnecessary ways, marketing it as “revolutionary” and “groundbreaking”
The majority of our oxygen comes from algae, they aren’t reinventing existing solutions they just put a tank of them in a city and blow air into it so that a city can use the same more efficient fauna that is available in coastal cities
I believe algae are flora, not fauna
You are absolutely correct and that was a stupid on my part
Mistakes aren’t stupid, they are human. Hell we are even making our AI in our own image now…
Back when I was a kid, trees still lived under water.
trees are not as profitable
Green shit on your terrace, leaves fucking everywhere, looming threat of bird shit on your head, seeds everywhere, roots growing through everything, blocking the sun at every step, tough lessons in gravity for things kids climbing them, lot of damage when it’s stormy out.
But nah trees are great, really.
Gray shit on your everything, concrete fucking everywhere, looming threat of 2-ton steel death machines caving in your head, overheating everywhere, asphalt plowing through everything, soaking up the sun at every step, tough lessons in momentum for kids crossing them, lot of traffic and pollution when there are drivers out.
You could change half of your words, and keep the meaning the same, and make a compelling case that roads, or any other things, are humanity’s greatest scourge.
If all you can do is complain that the natural world is insufficiently bent to your personal convenience, you are the problem with humanity right now.
Go touch whatever remaining local flora people like you have allowed to continue to exist, and quit being an imbecilic bellend online.
blocking the sun at every step
That’s a feature. I don’t want to be grilled by the sun everywhere I go.
Great for local air quality, too.
Oh no, nature is getting in the way of…a civilization of bipedal animals that encroached on nature!
It’s abhorrent!!
The problem with trees is they are used as lumber. The national parks has always been protected. But Trump has unprotected parts of the national parks to be cut down for lumber.
Trees take ages to grow, and their root systems damage buildings and pavements.
But the shade of a tree is far superior and reduces the overall temperature around them if many are planted, so overall much better.
Also certain trees dont need deep roots and can grow without neccessairliy damaging the pavement.
You can take trees and replant them in the city, you don’t have to grow it there. There are tree farms.
Also really really hard to keep trees alive on the sides of buildings where these units could conceivably be used. Modular trees plus trees where we can fit them.
Insert random copypasta about biotech breakthrough that turns water and CO2 and nutrients into sustainable building materials which sounds like space age technology but it’s just trees
Trees arent liquid
We should build a giant sky with fluorescent lighting 24/7. Think of how wonderful the city would be with constant bright fluorescents.
Can’t they just put the algae in the ocean?
There are algae in the ocean. The problem with ocean algae is not that they aren’t there, but that their requirements (sunlight, oxygen, acidity, temperature, etc.) prevent them from expanding any further.
If we put the algae in the oceans, then sink all of our cities underwater, all of our problems will be solved.
Dumb take. If someone crashes their car into one of these, it can be replaced in a few days. Trees take decades to grow in ideal conditions. Between tall buildings in a city is far from ideal conditions.
Also algae is way more efficient at converting CO2 into O2; I think it’s maybe multiple times more efficient using the same amount of light.
As an emergency responder, I can say with confidence that when a car hits a tree, it’s rare that the car wins. The tree usually just shrugs it off.
Emergency responder in a big city? Trees will fuck up a car no doubt but not usually the tiny ones lining the streets of major urban centers, most I see get to be maybe 5 in across. But it may all be location dependant.
Yes. Even a 50mm (2 inches) tree trunk will usually win against a car on urban roads.
Dumb take, by the guy who has no idea how much it costs to maintain these tanks or any understanding of the scales involved, all while wanting to live in a world of green goo in tanks instead of one with trees in their cities.
