I really wish veg*ism wasn't presented as such an aggressive, black-and-white moral issue. When you tell someone that every time they eat meat they're committing murder, their only options are to change their lifestyle completely, feel shitty whenever they eat meat, or reject that narrative outright. Most people go for the last
But the fact is, our meat-heavy diet isn't sustainable, and we'll have to change it eventually if our species is to survive. So every step you take *is* helpful
Try to eat less meat. If you do eat meat, make less of it red meat. When eating plants, try and eat in season (and local, if possible). Try out some meat substitutes and meatless recipes - they're better than you think
But don't get overwhelmed trying to change everything at once, because by any measure you're better off doing a little than nothing at all
