Abortion empowers women. Abortion allows women to pick the time at which they choose to have children. Abortion allows women to pick the partner who will co-parent the children they have. Abortion results in children having better educated, more emotionally grounded, and more financially secure parents.
Stress during pregnancy is thought to be one of the causes of developmental delays for infants. Stress during pregnancy contributes to babies born underweight and/or pre-term. Post partum depression has long term effects on mother-infant bonding and can also contribute to developmental delays. Older children have lower IQ's if their mothers experienced depression in the first few months after pregnancy.
Approximately one out of every three women will have an abortion.
About one quarter of all pregnancies in the US end in abortion.
That is 1.3 million pregnancies per year. It is unlikely that, if abortion were made illegal, so many annual pregnancies could be absorbed by families and/or single persons looking to adopt. This would result in babies being raised by unwilling parents, or raised by the state, in foster care or the resurgence of group homes/orphanages (there are already approximately 150,000 children in foster care who are not likely to be adopted). A disproportionate number of these surplus unadopted babies would be non-white and/or non-healthy.
