What would you add to the constitution?

I would add to the constitution that abortion would be illegal all throughout the United States. I think it's wrong to have an abortion no matter the circumstances of how the  woman got pregnant. The baby inside the womb is alive and is a living person. In law courts when a person kills a pregnant woman the person is charged with double murder, so why isn't abortion consider committing murder. Having an abortion is a cruel way to get rid of your child. Instead of having an abortion, why don't you have the baby and give it up for adoption if you really don't want the child.
