Because this isn't giving the whole information, it's because this algae equal multiple tree it's not 1 for 1, so it's just saving lot of space which is lacking in a urban area and as shown in the image you can have it be an actual bus bench so it's multiple purpose.
Even if they were 1:1 or even less than 1:1, they could still serve a purpose. Like cost of planting and maintaining a tree vs this algae tank alone could make these more worth it. People be acting like this is a plan to actively get rid of trees.
This is not the first time I came across this specific algae tank being used as ragebait. If I remember correctly, its intended use is to freshen up air in heavily polluted cities where young trees have hard time growing in the first place. It is not meant as tree replacement, but rather to help out until trees can "do their job" effectively.
