These artificial trees could improve air quality in many cities

Strange trees have spread across this city in Mexico... This solution meant to improve air quality could soon be introduced to many other cities around the world.

    Why not plant real trees instead?

    Let’s not call it a “tree” when it is only performing one or two functions that real trees perform.

    Puede ser un arma de doble filo porque muchos intentarian reemplazar los árboles por eso

    I guess you could place those things in urban areas where trees can't grow due to lack of space or fertile soil 🤷

    Increible lo mal que estamos ! Tener que recurrir a la tecnologia para descontaminar una ciudad,con lo facil que seria sembrar arboles,el problema es de todos y hay que actuar. La ciudad se vera mas hermosa con arboles,el aire mas limpio. Este metodo saldra muy costoso,mas contaminacion visual,mas basura tecnologica. Vamos de mal a peor...😠

    What is the result? How effective is it? The whole video is like a commercial ad. to sell a product, nothing else is mentioned. If it is a tree, it is an ugly tree, without a shade for pedestrians, without flowers for butterflies, without shelters for birds, without fruits for tree dwellers! :(

    Everyone on here getting up in arms over "real trees", what is your deal? Not gonna complain about one of the thousands of urban structures you encounter every day (signs, traffic lights, newspaper stands, crosswalks etc.) , but let's criticize the device that cleans the air?? You're not an intellectual for thinking real trees are preferential to this, the same way you wouldn't be an intellectual for pointing out that natural breathing is preferable to being on an oxygen tank. First of all, the algae in the device is cleaning the air more efficiently than a tree would, so if the goal is cleaning air pollution "just plant a tree" obviously isn't a viable solution.. Second of all, we aren't replacing the trees. You can still enjoy the trees, go see a tree, etc. We can honestly have these things and still have trees lol, wtf.

    Would this work in areas with colder climates as well?

    Great idea, but would love to see urban planners work on fixing actual design issues so technology like this could be reserved for cities where restorative work is impractical.
