veg or non veg which is more in the diet

I think you can have both veg and non veg foods. I mean you can balance with veg and non veg while you eat. You will get both nutrients from both veg and non veg. You must prefer to eat those animals which are grown in diary farm.

Yes. Killing animals especially endangered species is incorrect, so try to avoid it as much as possible (morally speaking). Unfortunately I being a strict non-vegetarian, somehow always love eating non-veg, especially chicken.

I eat meat but not every day. We have cheese pizza for dinner once a week, and tonight I am making a pasta dish that does not have meat in it. I try to fix another meal during the week that does not have meat as well, but the rest of the week we eat some kind of meat, chicken or fish. We tried to go meatless a few years ago but it was too hard, and we were not getting enough protein and my husband and I both gained weight.
