Still and this is the big thing, these are all possible considerations, plenty of urban areas, once they reduce street traffic to what is seen in European and other areas could also vastly greenify areas via mini parks allowing root space (and tbh if it messes with a sidewalk well then fix it like what functional societies with infrastructure budgets doi). All in all this just gives off techbro “genius solution” grifting and likely isn’t even possible on a large scale given I swear I’ve seen this same tumblr reblog before and yet areas that are hard on trees (Like LA) still has a crap ton of palms and other trees not even remotely habitable to the climate.

A few reasons: Trees need a lot of space and the space underneath a sidewalk isn’t enough for long term life. They can die after like 30 years? This is tree dependent and location dependent.
Tree roots can destroy sidewalks making it harder for people to go over them. (Think people in wheel chairs)
Liability in terms of damage (have you seen trees after a storm?)

I should have mentioned this but usually stuff like this is planted in front of people’s houses etc. I wouldn’t expect a pine tree planted in one of those. Same with a palm tree.
I’m from Pittsburgh and there’s a lot of greenery projects and ecological restoration currently going on. Outside of the city, it’s very heavily wooded. But it’s slow progress.
Those giant algae tanks miss the large point of trees and their physical benefits and do feel like a tech bro solution looking for a problem.

fuck sidewalks, tree roots can fuck up entire buildings

My first thought, having lived in an area with trees but inadequate funding for clearing leaves, is that every sidewall just gets buried and slick with wet leaves.
Idk what the labour costs are for these things.

Not all tree species destroy sidewalks.

Sounds like we need to remove the need for sidewalks. Rip up all the roads in the city and replace them with green space. Problem solved
stray@pawb.social 5 days ago
I disagree. Pavement is valuable to pedestrians, cyclists, emergency and service vehicles, and the disabled. While it’s important to preserve nature as much as possible, some urbanisation is also a good thing. That said, I’m not sure algae tanks would be necessary in areas where huge tracts of land aren’t dedicated to parking. I can’t really think of where my city would benefit from them.

Yes to ripping up roads for greenspace, not to removing sidewalks too.
Make the citu green and walkable, and you solve so many problems in one go

If cities where walkable they wouldn’t be sprawling masses that they are.
