Why I am not a vegan

[Monica]

However, I think jumping from where we are now to veganism, (No domesticated animals, no farm animals, or animal husbandry ie. no dairy, no eggs ) might be tough. 

The world won't jump to veganism overnight, so it's a moot point. That is, unless/until they have No choice, which will surely happen in a few decades.

But with veganism as a goal, progress can be made.
