Short answer: the bank won't give your shiny new tree-planting business a loan as easily as it will to a "liquid tank tree replacement" one.

Long answer:

  • Trees take time to grow
  • Trees need to be planted
  • Trees make shade
  • Animals like birds and insects like bees and mosquitos like to live next to them
  • Trees don't need electricity
  • Trees take in heat radiated from the pavement
  • Trees don't look cool

While algae are more efficient at turning CO2 into oxygen in theory, in practice algae don't have a good climate in such a tank (no oxygen without ventilation, i.e. constant electricity and they get cooked through the glass).

All in all, more of a gimmick than anything.

Roots limit where they can grow without messing up infrastructure.

Trees don’t look cool

You take that back!

  • Trees take time to grow

Sure, of course not removing literally all of them in the first place is preferable but hindsight is 20/20 I guess. And good things come to those who wait.

  • Trees need to be planted

True, planting a tree seems a bit easier than installing a weird tank though, despite time to grow.

  • Trees make shade

Good.

  • Animals like birds and insects like bees and mosquitos like to live next to them

Good.

  • Trees don't need electricity

Good.

  • Trees take in heat radiated from the pavement

Good.

  • Trees don't look cool

Bullshit.

Aren't like half of those bullet points positives? Also in addition to what you said once you got a tree you got a tree, those tanks need constant maintenence and cycling which I doubt anyone is going to bother with for more than a year after installing them.

The comment you replying to was trying to not so subtly point out this is a business plot and little else. Nobody is going to pay a subscription fee to have a tree in front of their business, but they might cough up money for a third party to maintain a tank of algae out front if it was sold right
