It can be hard for a person to understand. But becoming vegan is very easy.
There are very many people turning vegan.
is hard to understand the importance of becoming vegan in our society,
it is hard to break from the cultural indoctrination since childhood,
which is continously reinforced by our society, including peer pressure.
it is wonderful that some people manage to break off from the
incredible disconnection that is created by our daily non-vegan choices,
and the loss of understanding, love and empathy, and harm that is
caused by these choices.
I recommend this article: http://www.abolitionistapproach.com/some-thoughts-on-vegan-education/
And the World Peace Diet by Will Tuttle (www.worldpeacediet.org) -- a wonderful and very enlightening book.
