- Henri Lefebvre, The Right to the City — In brief, the right to the city is the right to the production of a city. The labor of a worker is the source of most of the value of a commodity that is expropriated by the owner. The worker, therefore, has a right to benefit from that value denied to them. In the same way, the urban citizen produces and reproduces the city through their own daily actions. However, the the city is expropriated from the urbanite by the rich and the state. The right to the city is therefore the right to appropriate the city by and for those who make and remake it.

Like the video already outlines... lots of structural issues for having trees there, while planted cascades and similar green-roofs are much simpler and easier to build. I think this is one of the cases where the result does not justify the costs/efforts required.
Probably doesn’t make sense for standard residential buildings but for these tall buildings that are highly engineered, does it really increase the costs by that much? Trees offer a large increase in benefits over other types of vegetation due to the shade and many times greater biomass.
That said, simpler green roofs should also be more widely used in cases where trees are too heavy or expensive. And vines and green walls too. I want to see the concrete jungle become an actual jungle!
That huge below surface cistern and the efforts to anchor the trees against wind would seem to add significantly to the cost over artificial shading structures with ranking plants for example.
I suppose it would depend on the costs and benefits which I haven’t seen quantified. But in general those things don’t provide anywhere near the benefits trees do.
