We watched a video about this in uni today which was really interesting. Cochlear implants, which when implanted in a baby, can really improve their hearing and hence their speech development. The implants however, seem to face strong opposition in the deaf community. Some activists have labelled the procedure “cultural genocide” as there are fears it will lead to the decline of deaf culture.
What about deaf parents who want to screen embryos and actively select for deafness over hearing children?
