“there was simply no ethical reason to consume a mammal, whether a cow, pig, dog, or dolphin. Each of these intelligent species deserved security from slaughter, even if the responsibility for managing their numbers still lay with Humans.

Drop further to an insect or nematode—if that’s what someone really wanted to eat—and they wouldn’t get any argument at all, at least not from Daniel.”
