  Many, if not most, who support the use of human embryos for HESC research would likely agree with opponents of the research that there are some circumstances where the use of human embryos would display a lack of appropriate respect for human life, for example, were they to be offered for consumption to contestants in a reality TV competition or destroyed for the production of cosmetics. But proponents of the research hold that the value of human embryos is not great enough to constrain the pursuit of research that may yield significant therapeutic benefits. Supporters of the research also frequently question whether most opponents of the research are consistent in their ascription of a high value to human embryos, as opponents generally display little concern about the fact that many embryos created for fertility treatment are discarded.
