The Birds, The Fish, and The Bacteria

One day, as some birds swooped down from the sky to catch some fish, the fish said to the birds:

"It's not fair that you're going to eat us! We're victims!"

For whatever reason, the birds took this to heart, and decided not to catch any more fish. The fish then went on their way, until they decided to catch some bacteria. The bacteria then said to the fish:

"It's not fair that you're going to eat us! We're victims too!"

The fish, not wanting to be hypocritical, decided not to catch any more bacteria. The bacteria then went on their way, until they decided to catch the bodies of dead birds. The birds that were still alive said to the bacteria:

"It's not fair that you're going to eat us! We're victims as well!"

The bacteria, not wanting to be hypocritical either, decided not to catch the dead birds.  The birds that were still alive then went on their way, and now there were no victims in the ecosystem. Everyone was happy.

But then the birds started getting hungry. They couldn't eat the fish though, because that would be hypocritical. So they starved to death.

Similarly, the fish started getting hungry. But they couldn't eat the bacteria, because that would also be hypocritical. So they starved to death as well.

The bacteria were also getting hungry. They couldn't eat the birds that were dying of hunger though, because that too would be hypocritical. So the bacteria also starved to death.

Everyone was now dead, but at least there were no victims in the ecosystem.
