Is promoting veganism neglected and if so what is the most effective way of promoting it?

Abstract

Veganism covers more problems than one might think, deforestation, animal cruelty/factory farming, climate change, inefficient land & water-use, better health if we assume one doesn’t eat vegan junkfood. I’m sure i haven’t mentioned all of the problems it covers, but it’s a lot, veganism & promoting it seems very neglected. What do you guys think and if one were to go about promoting it what would be the most effective way?
