What survives

Deep in the forest the squirrels are quiet,
Something is coming that squirrels don't like.
Humans with rifles are coming to shoot them,
Nuts to all that!  They will all run and hide.

Swimming against all the cold rushing waters,
Game fish will struggle as long as they can.
Sensible fish, though, show much more acumen,
Following water that's rushing on down.

Birds of the air and birds of the water
Share the bright feathers that dinosaurs wore.
Once long ago, before the great asteroid,
Birds would have sunk their teeth into our throats.

A little cloud, a little sky, a little wet, a little dry,
Another day as life goes on to find its own way.
