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.
