Abortion makes sense in every area--unless you believe that God made alot of souls 6000 years ago when he supposedly created the world-- or if you have faith that we all have souls and they are put in us at conception. There is no evidence for either-- except that a few men said they were true, so their followers believe them. They are certainly unprovable ideas.
But there are provable ideas that abortion is necessary. Too many people are the cause of climate change. We blame the carbon dioxide that they use and the beef that they eat--but too many people is the root cause.
This book looks at the more obvious negatives to the opposition to abortion. There are far more reasons than just the desires of a pregnant girl.
