如果我以右邊的漫畫來反對吃蔬菜，相信大家只會覺得我是瘋了。但有些素食主義者卻常以左邊的一類宣傳手法來反對吃肉。

在一個火雞能開口談論感恩節的世界，粟米當然也可以有眼耳口鼻。
火雞是生命，粟米也是。
有人會說火雞是較高等的生命，但人類的等級豈非更高？如果雀鳥可以吃粟米，人類為何不能吃肉？

我一向都覺得要推廣素食主義，最強理據當是資源使用效率與環境保護。訴諸道德根本行不通。

If I try to argument against eating vegetables with the comic on the left, people would probably find me ridiculous. Yet some veganism promoters still believe comics like the one on the right work.

Turkeys are as likely to talk about Thanksgiving as corns have eyes.
A turkey is a life, so is a corn.
One might say turkey is a much higher form of life, but then human would probably be even higher on the scale. If birds can eat corn, so can humans eat turkeies.

I always favor the environmetal efficency argument for veganism, for the moral argument really does not work.
