response: How do you feel about it during the Stone Age? The period where stone was the material used to make things.

history: Vegetarianism, or the Pythagorean diet, has been around for thousands of years, going back all the way to ancient greece. Did you also know that sea animals fall under the animals to not be eaten? Yes, and you could also say that our paleolithic and neolithic ancestors also practiced this diet, as they consumed mainly a plant based diet ( plants can't run away ). The Mesolithic era is what occurs next after the Paleolithic. What do you think about that one? well, in the mesolithic, people became sedentary farmers and began to keep animals as food, if you trust the archaeologists.
knowledge: The Stone Age was a broad prehistoric period during which stone was widely used to make implements with an edge, a point, or a percussion surface.
