a hungry lion or wolf does not eat animals from places like this
lions and wolves and all of the other land predators combined are are not eating even close to the same amount of animals as humans do.
Producing animals in these quantities is completely unsustainable. Animal agriculture is one of the top causes of greenhouse gas emissions and deforestation.
Lions and wolves do not have the technology to grow large amounts of nutrient-rich plant based foods. They also do not understand nutritional science, and don't know what nutrients are required for them to live healthily.
Lions are obligate carnivores, and need meat to live healthily. Wolves are non-obligate carnivores, and can live healthily on plant-based proteins, if they had access to them, which they don't. Humans are omnivores, but physiologically much closer to herbivores than carnivores. A vegan diet is closer to what our bodies are designed to eat than the average western diet (meat every day). Wolves and lions do no suffer from high cholesterol, heart disease, colon cancer, prostate cancer, etc like people do. All of these diseases are linked to meat and dairy consumption.
To a wolf or a lion, eating meat is required for their survival. For humans, eating meat is a luxury that unnecessarily harms innocent animals, global ecosystems and our bodies.
