Next time you hear somebody complaining about how “overpopulated” the earth supposedly is, you can respond by saying “I guess we need to start killing all the pets, then?” Or better yet, “So when are you going to kill your pet cat?”
Personally, if we’re discussing overpopulation, I would certainly prefer to rid the earth of a few humans rather than dogs. Other than chewing up a few slippers or furniture legs, how much damage have our furry friends done to this world?
