consider the power found in tiniest microscopic seed??

for centuries we dig, spray chemicals, burn and still the flora lives. we cover up many acres with concrete and asphalt and still those weeds find a way to grow without any nurturing by mankind. bulldoze, bomb and nuke the ground and plantlife will thrive as the buildings deteriorate and crumble into dust. we must harness and put to use all that energy found in the seed. why havent we already??
