Veganism doesn't exist because it is impossible that the human doesn't have any proteins. Vegans must take protein pills, so vegans are eating meat in the end. There are alternatives diets, but it is only a dream to try to find a substituye. "Veggies" are nothing without the meat and for example vegan cream of rice, if it's cream of rice as isn't vegan ! The companies win a lot of money with that thing.
