So I think the general idea is that you can convert more CO² to carbon in the form of sugars and O² molecules per square foot with algae than with trees. Trees would totally do the same thing if we ripped up all the concrete and buildings to replant a forest, but that process would take decades.

This can be added into existing infrastructure and helps I guess. Kinda a neat concept.

Exactly man... fewer floods, more biodiversity, they look nice which is better for mental health and reducing hypertension (the number one risk factor correlated with deaths), some of them give you fruits or nuts to eat... Trees are awesome.

I think any city should strive to have at least as many trees as the number of people living in it.
