This just makes me think it’s an aquarium that needs to be cleaned.

I recently learned that there's a group dedicated to planting 1000 trees in the city of Trenton, NJ, USA. I'm really glad to see a city working to bring back a little nature!
In Vienna, Austria, Europe, every tree removed has to be replaced with a new as per regulation
Same in Oslo
The problem even with that is that an old, standing tree and a young one are very different in their ability to provide the services we seek from them.
I guess the "problem" with trees is obvious: it takes decades for them to produce the desired cooling effect in urban areas. You plant a dozen young trees today, you can begin to reap the cooldown 10 years later at best. Also, they need a lot if water, and many of them just don't make it - urban surroundings are just much hotter and more stressful (smog, salt...) then standing with other trees in a forest. I fail to see though how these artificial "trees" pesticide any kind of benefit at all.
The amount of water required is trivial compared to most other water uses. Especially if correct species are selected.
The London plane tree is particularly suitable for urban areas, it's resistant to air pollution.
True, but unfortunately, this species is way over-planted in many cities. I would not recommend them unless they happen to be uncommon in your local area. Urban forests need to be as diverse as possible to resist the constant barrage of pests and diseases being introduced by global trade.
In California we have a relatively new pest called shot-hole borers which are killing off many of the London planes, so we’re scrambling to plant other species that can resist them.
Also, resistance to air pollution isn’t as crucial as it once was due to better emissions technologies.

I think the problem is putting them in those dumb tanks where a tree would be, as if to say "do this instead". The principle would be fine if they got a bit more creative with it and played to its strengths, e.g. if you make a train platform out of it, or the railings of an overpass, or the external wall panels of buildings etc.
Ofc OOP didn't actually provide a source so we've no idea what the creators were actually thinking...

Trees don’t attract VC funding the way some dumb new invention does.
I guess this could be useful in places trees don’t fit but I think there are other simpler solutions.
useful in places trees don’t fit
I have a tree sitting in a pot on my desk.
Does its root structure break the pavement above it?
Your potted tree isn’t a tree in the sense that I’m talking about. The environmental services trees provide are all based on size and so are predominantly provided by larger trees. Cities usually avoid planting these under electrical wires and in smaller tree basins to avoid damage to infrastructure. So practically, there are many urban locations where big trees won’t fit.

Trees don’t create shareholder profits
useless pests they are. who cares that they provide free shade, free oxygen, free beauty for all to enjoy. Fucking commies.
I agree trees are commies. Must be why Trump is going to clear cut several hundred million acres of the last remaining old growth forests …because they’re full of commie trees
What happens when one of these breaks and drains into the sewer system? Algae blooms cause noxious odors and would proliferate quickly in the nitrogen-rich environment of human waste water, potentially building up as clogs in the sewer lines. And if the system drains into a natural body of water, the algae can have devastating toxic effects on the natural wildlife. If it doesn't drain and instead gets recycled, then the water treatment process becomes much more difficult and expensive.

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.

even your trees will be slop. nice.
People really like vandalizing trees, diseases exist, and they are less efficient carbon sinks
Like how we found it’s better to feed cattle seaweed than grass but nobody wants to because it’s different
Carbon sinks? Dude, people are planting trees in cities for the shade.
There’s a quote about planting trees and not living to see their shade
I’m a bit more pessimistic of people plus with smog cover how often will they need shade?

Good thing people don't like to vandalize glass.
ITT: People who looked at some random headline, didn't bother looking further and assumed they knew everything.
It's a stupid headline. These tanks, are to directly affect air polution/quality in urban areas. Trees are terrible at that. The microalgae is 10-50x more effective in cleaning the air.
They aren't going to rip out trees for these. It would have taken you 10 seconds to find the source of the image and the article from 3 years ago to find out, the social media post was misleading. You spent more time making incorrect and wild accusations.

The problem with trees in an urban setting is trees have roots, and these cause issues. The can damage pipes and other underground objects. And many trees that are designed to not have these issues, end up with stunted/damaged roots which severely effects the trees growth. Planting trees in urban settings take quite a lot of pre-planning, and aren't drop in solutions, and if the areas weren't originally designed with trees in mind, you are likely to cause more problems than solutions.
