From what I gather, There are animals or animal eggs that are protected , especially if they are endangered. You may need some type of permit to have access to those animals.
Perhaps some pro-choicers may accept the human rights to the unborn if it was endangered (Risk of extinction).
This is about the purpose of animals and their values.
Animals is quite different. That is why animals can't be punished the same way cause animals are not bound by laws that we humans have. We are responsible for all animals on this earth and have laws given to us on how we treat them. The values we provide for animals is different from humans.
So it when it comes to humans. What is our purpose? What value should we hold for the life of the unborn? What is the purpose of the baby being in her womb?
As a pro-lifer, I say to live. Their life is valuable.
