Is a dog's life more valuable than a human's?!?!

I just wrote the following letter to the editor of our local paper.  It is indeed strange, isn't it, that some are so concerned (and sometimes rightly so) about the ethical treatment of animals, but turn a blind eye to the welfare of the unborn.  It's so hard to understand.  I'll let you know if they publish my letter.

Dear Editor,

I was struck by the irony of your front page story of 4/28 on U-M's repayment of grant money used for animal research.  People for the Ethical Treatment of Animals wants the National Institutes of Health to revoke its approval for U-M to use animals in federally funded research because of a number of incidents where animals suffered accidental injury or death.  I don't recall any outcry by PETA over U-M's announced intention to do research on human embryos.  This research will require the deliberate destruction of human lives.  Yes, embryos are ethically and biologically human.    Is a human life of less value than a mouse or a dog?  There is something wrong with this picture.
