Step back a little. Why are there places in cities where trees "can't grow"? What's the problem - water, land, sunlight? And why not fix whatever is keeping trees from growing, and then grow trees, instead of dropping in a tub of algae? And if these tanks are 50 times more "efficient" than a normal tree, how much more expensive is manufacturing and maintaining them than planting and watering a tree is?
This feels like carbon capture technology to me - a technological patch on a social and ecological problem, meant not to help the environment but to funnel tax money to venture capitalists and tech companies in the name of environmentalism.
That's without mentioning the resources invested into building those oxigen farms. The fact that this is done on a rich country already tells a lot. Solar panels aren't made with love and care, but minerals extracted from the earth.
Also, our problem isn't lack of O2 or excessive CO2. Our problem is a series of ideas and decisions we make about how we treat the world we're a part of. One of those ideas, is precisely efficiency above all other things. It's the same idea that makes market speculators fall in love with "line goes up". She even makes a point of saying how much more efficient than trees those are.
Sure, those are efficient in making the air safer for humans, but do they help with other local biodiversity? Do they help fixing the soil? Do they help the global ecosystem as a whole?
