As a vegan and a Buddhist I find the fact that people have to kill anything unfortunate, I woke up to this truth last year, however, as my friend Ian pointed out once, we only tend to want to save the cute animals. What about the billions of other animals like cows, horses, chickens that die every single day in often horrific and painful circumstances?
Human beings are brutal creatures, we have been since we left caves and tribal roots, but we are evolving at an exponential rate. A plant based diet is not only beneficial to your health it is beneficial to the environment, and if you are suffering from diet related illnesses or obesity it could save your life. You only need to take a look at the China Study https://en.wikipedia.org/wiki/The_China_Study To see evidence of these claims.
