Born Twice Article

Download file "BORN TWICE.webarchive"

Students - Please read the attached article called Born Twice. This article was published in 1999 and recently the child was observed. The child, diagnosed with a severe birth defect, is thriving today. Surgery was performed on the child/fetus before birth. You will notice in the picture at the end of the article - this is showing the child inside the uterus holding the doctor's finger. Some have found fetal surgeries to be unethical and extremely risky. Please read the article and make a comment.

You are required to:
1) Make your own comment concerning the article.
2) Respond to two other comments (from other students - can be from another class).

This must be done by Monday, March 14th by 6pm.

Happy Reading!
