The other issue I've seen is that people that jump quickly into veganism from climate change reasons alone, is that in those moments of "weakness" later on, they're much more likely to relapse, and go straight back into eating meat. When there's a more fundamental change on an ethics basis (i.e. you do a mental switch and stop looking at that stuff as food to be consumed at all), then the changes seem to be more long lasting. Then it stops being "I shouldn't do this" to "I can't do this".
