    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?

        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.

      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.

      trees dont ruin ANY human infrastructure. But the usual urban infrastructure isnt well thought out enough to exist around trees. But smarter urbanism is possible and in fact does exist.

        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

      “let’s uproot all these trees and invade this space. and when the roots of the few remaining trees do what they are supposed to do, let’s blame them for ‘ruining’ human infrastructure!”
