intellegent,
The halachos of karbonos do not apply at this time. Animal skins are needed for parchments of mezuzos & sifrei torah. There is an inyan of eating meat on yom tov, but that is because of simchah, so if someone can’t/ doesn’t want to eat meat then this wouldn’t apply to him. So as far as I can remember I’d say that the torah doesn’t require someone living in present times to actually eat meat, but please correct me if I’m wrong.
Personally, I do eat meat/ poultry/ fish.
