S. Matthew Liao, a professor of philosophy and bioethics at New York University, during a 2016 panel discussion at the World Science Festival, suggested the potential use of genetic engineering and hormone therapy that could result in birthing smaller, less resource-needy children
Liao also suggested re-engineering humans to become intolerant to meat, perhaps introducing a pill that humans could take or even re-engineering the cow to make its meat poisonous for human consumption.
