I gave up red meat about 10 years ago. Pork about 5 years ago. Chicken about 2 year ago. I eat turkey on Thanksgiving and Christmas. We get "kosher" turkey, cuz they say the animals don't suffer. Tastes incredible. I do eat seafood, but sparingly. Tomorrow night I'm going out to dinner with my cousin, and I'll probably end up ordering a scallop dish. Love scallops. But I can go months on a strict veggie diet. Lots of chick peas and pasta, fruits and veggies. I have high blood pressure and high cholesterol (both hereditary) so my diet is good for me. Every now and then I will get cravings though. Just the other night my neighbor was cooking bacon, and you could just about see a cartoon scent waft into my apartment window. But then I really think about bacon and my stomach turns.
as a keen diver whose caught more than my fair share of scallops over the years and taken them home to gut and eat , i can tell you now the scallops suffer immensely .. you have to prise them open , ripping the poor thing then you have to use a knife to separate it from the shell ..all the while whilst it is still alive ..often they are still pulsing (probably death throes ) when you chuck them in the pan
Somehow the idea of killing and eating a mollusk that lives in a mudbank doesn't seem in anyway similar to killing and eating a mammal. But at the end of the day, we all make compromises in many different ways. You may be right that scallops suffer, and feel pain, and maybe even the emotional distress that comes with pain. And you never know, I may phase out seafood from my diet altogether too...
