Dolphins and, perhaps, whales are pretty intelligent creatures. In fact, they are so intelligent that some scientists think their consciousness is sufficiently humanlike to justify giving them rights that we don’t even extend to human embryos and fetuses. I can only imagine the wingnuts’ minds exploding. “I can’t harpoon a whale, but my girlfriend can get an abortion?”
I don’t really have an opinion on this topic. Life feeds on life. Some people are cool with that, and others spend all their waking lives wishing it weren’t so. What makes a creature above killing and grilling other than same-species solidarity? Is degree of consciousness the key? Is that why dolphins don’t eat humans?
As should be obvious, I’ll talk about anything to avoid pretending to care about who successfully bought an Oscar Award.
