Moss in concrete cracks

Moss has taken over a crack in the concrete. This is concrete in the yard. The builders made the concrete in squares. Each square was edged with a thin sheet of USB. 7 years have passed. Instead of YBS there is now moss. The moss probably grew on the USB leaf. This moss is a tough guy :) He will survive anywhere :)

And this is a video of another moss
