Always think in terms of pre-requisites that you need to achieve a goal, then break down those pre-requisites into the pre-requisites to achieve those pre-requisites.

If your goal is, for example, animal liberation. What do you need for that? Presumably legislation. Ok, so what pre-requisites are needed before we can get legislation? Well you need everyone to agree on what the solution is. Ok, so what pre-requisites are there to people agreeing that a solution is needed? Well you need everyone to agree that a problem exists. Ok, so what pre-requisites are there to everyone agreeing that a problem exists? Cultural awareness maybe(I'm not sure). Ok what pre-requisites are needed for cultural awareness? Organisations to lobby people and build that awareness. Etc etc etc.

Eventually you break it down to a strategic action that should be taken NOW and followed through.

Other future actions are fine to discuss, but they're just theoretical when you're in the wrong stage of the movement. The strategic actions to take currently comes from knowing where in the current movement you are. I believe that for the people wanting to pursue changes in meat eating and animal rights in the world to achieve their goals they probably need to work from organisations dedicated to that goal in the first place and build a cultural revolution around it.
