2. Milk
While milk can’t be directly genetically modified, cows producing it can. Even before Dolly the sheep, genetically modifying animals was causing huge controversies. Herman the bull was the first genetically engineered bovine in the world. Chinese scientists claim that they have successfully integrated human genes into cows, allowing them to produce human milk. Their New Zealand counterparts have engineered a cow that produces low lactose milk, allowing people who are lactose-intolerant to consume it. But perhaps the most promising genetic modification comes from South Dakota, where scientists are trying to create a cow that produces milk with human antibodies that can be used as a treatment for various infectious diseases, including Ebola and flu.
