What has been of particular concern to my committee is to avoid providing an incentive for the creation of embryos for destruction by research. That is a very difficult and dangerous area to get into. That is where this discussion endlessly goes around in circles. People want to use these stem cells to alleviate suffering, which is an ethical question in itself, but how does one do it without a situation arising in which one would be creating life in order to destroy it? That is a real ethical conundrum on which I would welcome the comments of Members.
