These are grass seeds, coated in plastic. Mix them in concrete, pour a pad, construct a building over it, and nothing happens. Not until years later, when Wal-Mart has gone to the other side of town, leaving only that unsightly and indestructible pad. A year or two of exposure to rain, and the polymer
softens; the seeds begin to absorb water. They begin to grow, developing hydrostatic pressure, pushing against the concrete. A web of almost invisible cracks form in the surface, and more water seeps in. It’s an accelerating process. Within months, the once monolithic structure is reduced to gravel, covered with tall fescue.

A fine idea. However, why not do this with crop seeds? In the event that society collapses, periodically some maize or okra will spring forth from the decaying rubble. Our degenerate descendants, clad in foraged 2-liter pop bottles and their own blue mutant fur, will find these precious gifts, cultivate them, and begin civilization anew. |
