At What Cost Do I Live?

My life is not my own
I am the culmination of a thousand generations,  
the intersecting interplay of the efforts  
of a million laboring hands  
 
What do I give, what do I contribute in turn  
for the opportunity to simply be alive?  
Subtracting cost from revenue,  
am I merely an expense?  
 
As I venture into the world each day,  
I send out ripples,  
like the bow of a boat  
skimming through the ocean,  
crests and troughs gently (sometimes not so gently)  
jostling other travelers  
 
I poison the air;  
I lay waste to earth's resources;  
my very home lies on stolen land;  
I take and take and take,  
my lust having no apparent bounds --  
a minuscule parasite hitching a ride on the universe  
 
Though by accident of birth, I was born rich  
--perhaps not literally, but in relation to too much of humanity--  
my 'wealth' comes at the expense of so many others  
And it seems it will never be enough

Why do I continue to exist  
when so many others better deserve  
the appellation of human being,  
and yet do not?  
 
Is Nature (dare I say "God"?) really unaware  
of the concept of justice?  
Or is the reckoning still to come when the accounts are closed,  
and balances checked  
and found severely wanting?
