Trees and algae have different utilities. Trees are beautiful, reduce temperature, offer shade, and produce a modest amount of oxygen. Algae tanks produce vastly more oxygen by volume and cause you to question whether it’s really enough to continue meandering through life in this stone and metal postmodern hellscape and maybe it’s okay to finally indulge in a vacation near open fields and untamed wilderness. The local camping spots might be available in a few weeks if my sanity can hold out. One doesn’t completely substitute the other.
I don’t even understand which part of the tree experience these tanks are supposed to replace. Are they really just there to pick up CO2? Because you can also plant a forest outside the city for that.
You’ll miss out on all the other tree benefits, but so you also will with these glass tanks.
