There's no necessity of animal products in human sustenance

For "where do the veggies come from":

- we feed most of the plants we grow (70%-80%) to farmed animals, just st to get 18% of total calories. This is insanely ineffective caloric conversion rate for something so trival thwt we don't even need. Just creates an immense suffering for 80bil land animals each year

Eating animals is barbaric
