Some people take the view that unless animals themselves can speak out to will not be possible for anyone to devise what they would call a really comprehensive, equitable "animal welfare law." Nonetheless, research related to animal welfare is still on the increase.
雖然有人認為除非動物自己發言，否則誰也無法定出一套所謂真正全盤、合理的「動物福利法」，但動物相關福利的研究仍持續增加。
