In a similar way, if you reduce your meat consumption by 80%, you're 80% of the way to the environmental benefits of a wholly vegan diet. Isn't it easier to convince someone to reduce their meat intake than to eliminate it completely?
My favorite trivia here is a study which documented that, of people who self-describe as "vegetarian", one third will admit to having eaten meat in the past one (1) week.
I eat mostly vegan and I have a bite of meat from my partner's plate about once a week. I want to share in her culinary experiences.
A week has 21 meals. If you eat 3 types of food per meal, you will make 63 food choices per week. A person can choose meat for one of those 63 choices (1.6%) and still be a vegetarian. Many folks choose meat for 30% or more of their diet.
I don't know where you get your definition of a vegetarian.
Eating meat 1.6% means your NOT a vegetarian, it just means your 'mostly' vegetarian.
I'm not saying there's nothing wrong with people eating meat, but most vegetarians I know (myself included), who are in it for moral reasons would take offense at that definition.
Maybe a lot of people want to try and be a 'vegetarian' (I dunno to sound cool?), try it for 3 months and fail constantly. These aren't vegetarians, just pretentious.
I've been a 'veggie' for 25 years and I haven't eaten meat, nor anyone else who I know who are.
80% of "sometimes" or "not every day" is still "sometimes" and "not every day".
People have no clue about how frequently they eat meat. Since vegan and vegetarian diet are gaining traction, everyone is pretending they're being careful and eating less meat than before, yet the global meat consumption is still increasing.
Global population and wealth are increasing. Meat is expensive. And price - we subsidise farming - is a direct way of influencing how often people eat something.
