Sharks, Dolphins, and Whales *are not fish*. How can i stop this?

I'm going to say this again: SHARKS, DOLPHIN, AND WHALES *ARE NOT FISH*. The *wrongful classification* of those marine animals have lead to mass slaughter of whales and dolphin for food, medicine, and research. Sure, there is some protections on mass killing of whales, but dolphins and sharks are still largely targeted. We can't get them to stop killing these marine animals, and nobody cares about how endangered these marine animals are.<br><br>How do I make people know what they are doing wrong?
