I have been reading a lot about vegetarianism. Are you on any special diet. 
I just try to watch what I eat. I have heard vegetarianism has its roots in India and Greece
I am a environmental vegetarian I guess. Industrial animal places are bad for the environment and meat isn't good for humans , or so I've read.
I understand why people practice veganism. Most people do no want to harm animals and prefer a plant based diet.
Supposedly the human digestion system or colon is much longer than an animals because we are supposed to have a plant based diet as opposed to the short colons animals that eat meat have.
I remember reading about some monks who did not eat any meet or use any animals products. But they did choose to eat fish so I guess they were not full vegan.
