a human-scale measurement

I have wondered what impact I have on the world.  I am not a powerful, charismatic leader, nor a scientific or cultural pioneer.  I am a pretty ordinary individual... just one of billions on this planet.

I believe humans are big brained primates that dig in the ground, pick up and pile rocks, and leave some litter around.  I have done that.  Evidence of my being here is the cairn in my garden.  It witnesses my existence.  I was here.

I am here now.
