We never give much thought, Thinking we are standing, On solid ground every day, There is always something moving, Below our feet, over forty - one thousand, Earthquakes, in the year twenty - twenty That’s just in the U.S.A. Then if we think of all of the void spaces, Empty mines, caverns & caves… Many of us living above, under - ground holes, While the oceans, along our country’s east & west sides, Wash away, acres A year, with high tides, and waves.
