So, what's the difference between a vegetarian and a pescatarian?
The fish part? (...I thought vegetarians were still in debate over fish...)
I'm not so much worried about what I'm eating (meat vs. veggies), but rather how far it traveled to get to the store.
With all the gas/oil issues, it just doesn't make sense to me to eat foods that are out of season, or traveled farther than, say, 100-200 miles to
get to my store and plate. I don't remember exactly which page (I can look it up if anyone's that curious), but in Barbara Kingslover's book
Animal, Vegetable, Miracle, she mentions that for every 1 calorie of food we ingest, 87 calories were spent to get the food to us.

That
seems ridiculous...
Likewise, bear in mind that animals and insects lived in and around those veggies and fruits, and were stripped of their habitats, if not their lives,
upon harvest. (Not meaning to down-grade the efforts, just providing more information.)
