complete abolishment of animal agriculture is not done overnight with in one fell swoop. It’s done with small changes here and there. Slowly forging a new culture where it is considered worse and worse to treat animals badly. (and what counts as animal abuse will start covering more and more things). Slowly changing the norm. Same goes for privacy, user rights, etc. There are of course some key moments, watershed moments, legislations (GDPR for example), but those had a long journey of tiny steps all over the world before they came into being. Sort of like tectonic plates building up tension over tens, hundreds, thousands of years before they snap into place in one huge earthquake
