Nature

Nature will kill you without thinking twice,
There is a long term plan that you are only
A small part of, as long as you stay within
Her parameters. I'm talking to you, T-Rex.

Nature is not worried about your feelings,
If you are in the way of progress, she will
Let you know by wiping out you and all your
Friends, do you hear me, Hipparion, you three-toed horse?

And if you are driven extinct by the foolishness
Of some other species, don't look to Nature for help.
She has other things on her mind, Passenger Pigeon,
Your last three kin will live under glass.

Nature does not tolerate dissent.
It's just a matter of time before we all get
Our come-uppance. Someday our names will be
Added to the list. If anyone is still keeping track.
