This screenshot from the start of Earthlings holds a lot of truth in my opinion. Our societies now display characteristics of all three, and we can all think of individuals who are quite clearly at one of these stages. As long as we keep moving away from 1 and towards 3 we are going in the right direction :)
yes you're right! I know a lot of people now who tell me they know how terrible the food industry is, but "are not strong enough" to give up animal products. I don't really know what to make of this category...
I think perhaps a lot of people simply don't know how to cook without meat. It requires a lot of self education which not everyone has time for in their busy lives. It is unfortunate.
I think the second category could also be "in denial". That's where I'd put those people. Some are in denial about how easy it is to change, some about how bad it is, what they have in common is that they both have their heads in the sand.
