Embryo Factories?

The blogger at Shots Across the Bow poignantly points out that embryonic stem cell research, if it ever actually results in cures for common and serious illnesses, would only be the first step in the process. In order to make available those cures, it would be necessary to manufacture literally millions of embryos in order to create a supply stream for providing the treatment. Will people really accept the idea that millions of tiny human lives will be created for the sole purpose of stripping them down for their parts?

It will be a cold world, indeed.
