Moss is the first life form on land, the origin, the beginning of cycle. The water fill for it, fine stream flow through the little gap on the rock and bring the nutrient it need. Our ancestor live the same moist place, and now we are at the end of cycle. It’s our mission, our liability, and our fate to fulfill the cycle of life.
