This practice is an instrumentalisation of woman body: the most deprived woman rent or sell their body. The maternal bond develops before birth in the mother's womb and surrogacy breaks these bonds that develop between woman and fetus during the preganancy. This practice is inhuman for the woman and the child.
True, but the only reason why it would be forced on woman in modern societies is because the child has been neglected or abused. The social services just don’t walk around removing children for no reason. After all, it is the court who has the final word, not the social services. So the question is, should we (the society) be inhuman towards the parents and remove their child, or towards the child and let them suffer, potentially be killed due to mistreatment? Should we be worried so much about breaking the bond the child made while in the womb, that we let the parents do whatever they want to to the child, regardless how harmful it is?Adoption can be equally inhuman, especially if it has been forced on a woman.
If we really wanted to combat overpopulation, we would be focusing on those women.
Most people that undergo IVF or use a surrogate are desperate to have at least one child. There are families with multiple "traditionally made" children. Are they not polluting the planet?
