No animal will have to die for lab-grown meat. It is made from stem cells in incubators. And it is actually quite close to introduction into the market. Some is already sold in pilot projects. In a few years, it will basically be indistinguishable from "real" meat. It also consumes far fewer resources than "real" meat and can be produced much faster and cheaper. Further down the road, it might even be possible to grow meat from extinguished species like mammoths or make things like wagyu meat for a fraction of the costs.
