Humans Tweet on Twitter

Humans tweet on Twitter,
the subversive, the cultural,
sub-cultural, crucial, controversial,
and all that needn't occur at all.
Humans tweet on Twitter,
critically desperate images of birds,
and marine life and their indiscriminate
deaths, either from crude oil spills,
or pollution from disastrous
dumpings of man-made litter.
Alas, how humans tweet on Twitter.
