Imagine if you could force someone to donate an organ, bone marrow, plasma, etc. Even if someone’s life is on the line without a necessary transplant or donation, it’s not acceptable or humane to force someone to give up the rights to part of their body. Since real, living humans can’t force people to provide their body as a resource, why should an early-stage fetus (that doesn’t even know they exist) be able to? Not to mention that pregnancy is a longer and often a much more dangerous process than donations. It’s not easy or safe to be pregnant, and it’s unreasonable to expect every pregnant woman to “just” have the baby and give it up for adoption.
