ITT: People who looked at some random headline, didn't bother looking further and assumed they knew everything.
It's a stupid headline. These tanks, are to directly affect air polution/quality in urban areas. Trees are terrible at that. The microalgae is 10-50x more effective in cleaning the air.
They aren't going to rip out trees for these. It would have taken you 10 seconds to find the source of the image and the article from 3 years ago to find out, the social media post was misleading. You spent more time making incorrect and wild accusations.
Even with the misleading headline, has nobody commenting about how bad it is ever seen how many trees die when set up in low light conditions? These can be used in places trees wouldn't be effective, and that's before the whole "they're better at cleaning the air" bit.
Even with ideal light conditions, there's still more to consider.
I lived in Louisville for many years. It's fairly green as cities go. In older parts of the city, trees had been planted between the streets and sidewalks ... definitely a long time ago, maybe 30 to 50 years? Maybe longer?
Every spring, we lost a number of those trees to thunderstorms. Enough rain, followed by strong winds, would topple multiple trees. Every single one that I saw had a root ball that was exactly the size of the opening where it had been planted, so maybe two square meters and maybe a meter or two deep. (For those keeping score at home, that's not enough root volume to support a full-sized tree.)
So we'd lose those lovely trees and on a good day, we'd lose the use of the street for a while. On a bad day, someone would lose a car or a chunk of their house.
"Just plant more trees in the middle of the city" is not the brilliant fix that many people seem to think it is.
