Of course an anti-abortion web site would make a claim like this. It's bogus. And since when is a zygote considered a human being?
The website is taking into effect the use of birth control and babies not born because of using it.If the number of missing children includes those aborted by IUDs, RU-486, sterilization and abortifacients, the figure climbs to over $70 trillion
Do a google search on the author:
He's a rabid anti-abortionist. Of course he will write a story like this.
