Have you heard of veganism? We go way back to the civilizations of ancient India and ancient Greece. Where it all began. 
I have but im not a Vegan myself
Oh ok, Im what you call an ethical vegan, We are often applied to those who not only follow a vegan diet but extend the philosophy into other areas of their lives, and oppose the use of animals for any purpose.
Are you a Vegan youself?
Sure am, Ive been a vegan for 4 years, Are you interested in becoming one or would like to know more about it? 
I would what else should I know
Vegetarianism almost reemerged in Europe during the Renaissance, and became a more widespread practice during the early 19th and 20th centuries.
