Why it Should Stay Legal
Women should be able to do what they want with their bodies. It's a fundamental right. Although some people choose to abort a baby for non-logical reasons, abortion should stay legal for those who absolutely need that choice.
Unfortunate Circumstances for the Child
143 million children are currently in adoption facilities. No child should be born unwanted. Also, the parents could be incredibly irresponsible or live a bad lifestyle.
A Fetus is Scientifically not a Human Being
People say that a fetus should have the right to it's own body, but it technically is not a human being yet. It does not have the ability to live outside of the womb, so it is part of the woman's body and a woman has the right to her own body.
What would happen if abortion was illegal?
Abortion would not stop. Women would find ways to abort using very dangerous methods. So if abortion never will stop anyway, it mind as well stay legal. Women should be able to have access to modern technology to ensure a safer abortion.
