Being vegetarian is not without it's consequences. Trying to justify eating vegetables as a way of saving an animal is simply not true. Think of the millions of acres of habitat forever lost. Whether you harvest cattle or harvest a turnip it ultimately leads to the same consequence. I just wanted to say my piece.
Meat is entirely unnecessary, and therefore requires no substitutes.
Rather, flesh is a substitute for healthier, more humane dietary options. I have had personal struggles going and staying veggie. It was definitely nice to know that everyone at PAWS isn't a strict vegan or even vegetarian. Being busy with a move and getting ready for the baby and working full time left me little time to research what I needed to do to make sure I got everything I needed nutritionally, so I decided I'd eat meat just for the pregnancy. Then just while I breastfed.
