I think that trying to do this for wild animals, aside from being highly impractical, can cause unintended side effects. For example, one well known account of the positive effect of carnivores on their environment has been the story of the reintroduction of wolves to the Yellowstone National Park[0]. Aside from unintended side effects, I don't think we'd be able to find an effective way in practice to give all these wild animals fake meat and prevent them from hunting in the wild. I think domesticated animals and humans are a different story. While I highly doubt that any plant based methods will be able to replace a healthy carnivorous diet for obligate carnivores like cats, I have high hopes for cultured meat options in pet food. I believe there is already research and product development ongoing into this for dogs[1] [0] https://www.yellowstonepark.com/things-to-do/wildlife/wolf-reintroduction-changes-ecosystem/ https://www.yellowstonepark.com/things-to-do/wildlife/wolf-r...
