Far from there being a "right" to enhance oneself and one's progeny, some institutions and activists currently aim to outlaw various biotech interventions. For example, the European Convention on Human Rights and Biomedicine prohibits the introduction of "any modification in the genome of any descendants." While it does not have the force of law, UNESCO's Universal Declaration on the Human Genome and Human Rights urges nations to ban "practices which are contrary to human dignity" and specifically points to reproductive cloning. Bioethicist George Annas wants to go further and have the United Nations adopt a a Convention of the Preservation of the Human Species that would make efforts to enhance human beings by making heritable changes in people's genomes a crime against humanity.
