Neutrinos are the smallest of our problems
Gamma-ray bursts and blazar jets, just roast
Fast spinning, as they slice up the skies
To ensure no living matter, gets too close
Just one taste and you’re toast, at most
An Earth-sized target, is a curse
Sod Mars, we’ll hide in our hobby crafts
Behind our pale blue cosmic hearse
Homo erectus, stood tall with pride and sang
Reached up to the heavens, and abruptly died
Along came sapiens, floating in a can
Gave homo-artificial and homo-cidal, a free ride
