Dr. S. Matthew Liao, a professor of philosophy and bioethics at New York University, has proposed the concept of "human engineering" as a potential strategy to address climate change. In his 2012 paper titled "Human Engineering and Climate Change," co-authored with Anders Sandberg and Rebecca Roache, Liao explores biomedical modifications to humans aimed at reducing our environmental impact. One proposal involves inducing an aversion to red meat consumption. Given that livestock farming contributes significantly to greenhouse gas emissions, Liao suggests that pharmacologically inducing mild intolerance to meat could decrease its consumption. This could be achieved through methods such as "meat patches," analogous to nicotine patches, which would stimulate the immune system to reject certain animal proteins, leading to a reduced desire for meat. Another idea is to reduce average human body size, as smaller individuals generally require fewer resource...
