As the regular reader will know, we of Republic of Lagrangia are quite enthusiastic about in vitro meat. For non-regular readers, in-vitro meat is meat cultured outside the body of an animal, mostly in a lab. In order to do this, scientists have to collect stem cells from, for instance, a cow, which can be done though a biopsy. Since this does not require to kill the donor, some people consider in vitro meat as a more ethical alternative for regular meat.
Theoretically there no restriction on what animals can be used as potential donor for stem cells for the production of in vitro meat. Even meat from exotic or endangered species could be produced cheaply in this way. Practical considerations as availability of donor animals, and the demand for certain types of meat, will determine which meat will be produced.
There is no inherent reason why human stem cells cannot be used for the production of in vitro meat. And this worries some people. But why would this be wrong? If eating human is wrong, it’s mostly because we object to the killing of humans. Only, in vitro meat does not require the killing of the stem cell donors. Besides humans can, in contrast to other animals, give informed consent to such donation.
Republic of Lagrangia endorses classical liberalism as defended by John Stuart Mill. And a core idea of Millian liberalism is the so-called harm principle. People should be allowed to do whatever they want unless someone is harmed by such action. Given that people can voluntarily donate some tissue sample, and that no one is killed in the process; there is no way under the harm principle why cultured human meat would be wrong.
Although some people might object to the consumption of cultured human meat, we see no reason to prohibit people from voluntarily donating some of their own tissue for the production of human meat, or prohibiting people from buying such meat.
