      Algea is a much much better oxygenator with lower maintainence, people don’t seem to notice how fast cities can kill trees.

        You don’t need to put algae in cities. They can be basically anywhere to absorb CO2.

        Trees in cities tend to be carefully chosen for the environment. Are we in a climate where we need to put salt on the road in the winter? Choose trees that can tolerate some salt in the ground.

            As much as it sucks, until we reduce the need for cars, northern rural areas are going to need to use salt for roads to be usable. Of course, if global warming gets worse it won’t be an issue

              “Global warming” doesn’t mean warmer winters. It means extreme summers and winters and nothing in between, with a global temperature raising.

        And the oceans are incredibly vast, so they provide most of the world’s oxygen! Obviously it’s hard to get a precise number but 50-70% is the accepted range.

        There are many reasons to plant trees in the city but local oxygen supply isn’t one of them. Mostly trees look nice, and make people feel better by their presence. They also have a significant cooling effect, something a steamy tank full of warm algae definitely won’t help with on a summer day.

          Local oxygenation is important, conversion at the source pretty much always is.

          Moreover it doesn’t at all imply in lue of trees and importantly oxygenate at the same rate day and night since they’re independently lit ideally 24/7/365.

        My first thought is you can embedd this inside buildings rather trivially
