Scientists in Belgrade came up with the idea of "planting" large tanks of water and algae in places where trees can't grow. The tanks are 10-50x more efficient than a normal tree for the space it takes up and is in general highly sustainable, even creating excellent fertilizer in the process. You can skip about halfway through the video for the actual information about them.

Algea alone is responsible for about 50% of all of earth's oxygen. Trees and land plants make up the other half. Algea is incredibly efficient at oxygen production.

She cites a figure of 70%. Even better!

What I'd like to know is how much biomass these things produce after about 6 weeks you know since I'm I soil amendment nerd

At least enough for a little garden on the block!
