You mean like the ash from volcanoes
(or the radiation from Chernobyl) hanging
in the air for months and years, finally
sifting gently down on both anti and pro
*all around the globe*.
Seasoned cliches scream for attention: what goes around, comes around;
we're all in this together; think globally, act locally; we are all
downstream; divided we fall, united we go to hell together. Not sure if I
made that last one up. Probably not--there is nothing new under the sun.
