So when the rattle snake bites and kills someone its just natural selection? How do you explain to the rattle snake that you were just living in Harmony?
You know dang well if you let rattle snakes live in your back yard at some point someone is going to get bit.
I think its a complete contradiction that its ok to let the snake kill the rats. But not logical to kill the snake. The rats have to be dealt with by death because they are deadly and thats ok ? the snakes are deadly but are not to be dealt with by death?
How did rats get so far down the list?
Its clear that were just seeing a logical theory here and not a moral one. But logic wont work when you start asking questions.
What exactly are you getting to? Logic says that I'm more likely to die from a rat borne virus or bacterial infection. Snake eats rodent and ends the vector to me, as in, all viruses and bacteria fauna inside the rodent cannot live in the snake, ending the threat to me.
All I need to do is act accordingly, and not give the snake a reason to bite me by accident, by being a responsible property owner. Morality is not a trait that population ecology deals with. Whether or not the rodents die, is not my call. Naturally, they will move away from the area where they are dieing, by either forced selection (READ: EATEN) or by choice. The snakes will then follow.
It's really just that logical.
