"Wow, look at the beautiful Heron!" Well, not so beautiful if you are a newt!
A Beautifully designed/evolved killing machine and the poor newt, frog, fish or eel, goes straight down the Heron's throat into a pit of acid to it's death.
But this is the way of the world and we must accept it. We have evolved and learned enough to now be able to choose not to eat other creatures but the beautiful Heron has not.
Next time you see the sentinel of the stream, stop a while if you are unseen. Watch and wait, and wait some more... and see how life and death, beauty and horror, are inextricably linked.
