“so, a rock and a leaf fall into a stream...”

Ever wonder why we don’t see rock in igapo habitats? Are any rocks found in blackwater habitats? Well, they are, but the rocks likely didn’t form there.. the story of their formation and how they arrived in these habitats is a fascinating tale of incongruous elements coming together... so, yeah- You CAN have rocks and leaves together and be faithful to Nature...in context.
