Dr. Matthew Liao, a bioethicist with the World Economic Forum, recently proposed the idea of genetically engineering a meat allergy in humans to prevent them from consuming beef and other bovine products. Liao cited the Lone Star Tick, whose bite can cause a beef allergy in some people, as inspiration for this plan.

Why it matters

This proposal is seen by many as an extreme and unethical measure to curb meat consumption, which some believe is harmful to the environment. Critics argue that individuals should have the freedom to make their own dietary choices without being forced into allergies or intolerances.

The details

During a speaking engagement, Liao stated that he believes "refusing to give up steaks" is a "weakness of will" and that he plans to use genetic engineering to make people intolerant to bovine products. He cited his own lactose intolerance as an example of how human engineering could be used to create food intolerances.
