My local park has a population of 70 endangered birds who will have about 1 offspring each, and a population of 13 invasive birds who will have about 10 offspring each. To combat this invasion, my town introduced goblins into the park. The goblins eat about half of the invasive bird eggs but they also eat 15% of the endangered bird eggs. Park officials say that the loss of those endangered birds is necessary to keep the invasive birds population growth down, but every year there seems to be fewer local birds and more invasive birds. The goblins are also invasive and make a mess just like the invasive birds, so they don't belong in the park either. Apparently many of the park officials have goblin pets so there is clearly some biases regarding the policy.
I am betting on the "native species" in this case. They have a few tricks up their sleeves that have allowed them to survive the entire world history despite every obstacle being placed in their way. It may require culling some of the weaker members of the species, but this has been happening since the beginning of history and the "native species" is well-adapted to such ... violent ... changes.
Or, to be more clear, to those who understand the parable:
Anyway, after complaining to the park rangers, one day all of a sudden, for no reason at all, the park rangers were dead. The goblins were dead too. The invasive species were dead as well. The only survivor was the native species.
I guess that's why the native species were there in the first place.
Maybe I should've paid attention to the fact that they had sharp beaks and razor-like claws.
