Bees have-
Familes
Jobs
Pain
Plus they make honey, which is good for us
Humans have-
Families
Jobs
Pain

Anyway back to your question, we use tuna as food, not dolphins. Plus I'm pretty sure theres a lot more tuna then dolphins. Oh, and theres also the fact that humans like us automatically like friendly dolphins more then tuna.
