We might think that moss is just a nuisance that we have to deal with but way back in history it was a major factor in generating Oxygen that allowed human life to eventually evolve.

The choice is often between growing a tree or building something and unfortunately most of the time the tree looses. Now if we look at how much more oxygen moss can produce and how little space they need you can see a way to achieve both objectives. Which is what the Duch company called Respyre is doing. Respyre has created a type of concrete they call Mosscrete which is especially…
