I wouldnt go as far to say the pig is poison, like any other animal, you can eat it/them. What I pay attention to is the side effect after the consumption. Im a vegetarian. When I eat meat, my flesh gets redder and my digestive systel feels so differant, I feel like I shouldnt be eatting meat so I don't.
I wrote a panthlet on the science of the pig and most of the things said on this post are true to my knowledge. Whats iller is how certain companies take and use the pig and break it down to use as an element in just about any known material, from cosmetics to clothes. They make such a huge profit off this animal.
