I originally did it out of purely environmental reasons. I learned about the thermodynamics of food in my highschool bio class, and was astounded by the amount of wasted energy we were pumping into this destructive food system, not to mention after digging deeper into industrial agricultural practices and GMOs... wtf?
After I went vegan, I read more about factory farms (Fast Food Nation), and realized the there is no ethical argument for eating meat. I came to the conclusion that humanity will never have world peace until all life is respected.
Lastly, I practice a lot of martial arts, and saw a boost in my mental and physical health after I stopped living off death. Did some more research about human digestive systems and health.
There is no regret. This is the only way for me.
I'm vegetarian at the moment because I just really love eggs and I'm mad lazy. I plan of getting my own garden and raising my own chickens which I'll treat with love and respect (it's symbiosis, happens in Evolution all the time). 'til then, I'll always eat eggs with a guilty conscience, but I buy free range (whatever that means) in the mean time.
animals have the right to live and i am not a blind man. here in Brasil almost everybody eats meat...but i am doing my part.i dont eat meat since i was 18 (now i am 33).i have influenced some people to stop killing. kisses to you!
