Lab-grown mammoth meatball: A food stunt or the future of meat?

Australian startup Vow has unveiled a meatball made of lab-grown cultured meat using the genetic sequence from the long-extinct mammoth, which is meant to fire up public debate about the hi-tech treat. The cells were multiplied until there were enough to roll up into the meatball. More than 100 companies around the world are working on cultivated meat products, many of them startups like Vow. Experts say that if the technology is widely adopted, it could vastly reduce the environmental impact of global meat production in the future.
