Sometimes, I have an issue with this. If your reason for being vegetarian is purely because you believe that meat will cause you to lead a life of misery and early death, then while I won't be joining you in not eating it, I have to let that one go because maybe fish is better for you than other meat. Or if you believe that fish lead less miserable lives than other animals raised for meat in our society, then I guess I'll let that slide too. But if you have issue with eating another animal because you value life, then THIS is what I have an issue with.
If you value all life, then why does a fish have less right to life than a chicken? I mean, just because fish are all scaly and don't blink doesn't mean they're worse than kittens. I propose that if you value life, then eating a smaller animal like a fish or chicken is worse because more animals have to die to provide the same amount of meat. Whereas, one cow can feed a lot of people.
Thus I propose a new way to eat. I call it being a gigantavore. Eat meat from the largest animal possible so that the fewest number of animal lives are lost to feed the largest number of people.
Anyone know a good source of sustainably farmed whale???
