I'm going to try to articulate what I believe is logical and ethical. Please hear me out and please don't jump to conclusions about what I mean. My points are. 1) Since it is self evident that dolphins and other whales are intelligent beings like us and they need to eat fish to survive and evolve. 2) Since humans who eat specific type of small fish are the most attractive and tend to look like fishes. This indicates that the DNA from the fish is being absorbed and incorporated into their human genome and eventually passed unto their next generation. 3) It's unethical to buy fish from the supermarket because it comes from an unethical capitalistic source without regard of the damage that it is doing. 4) I believe it is ethical for someone to be independent of capitalism by catching their own small fish to survive, evolve and pass on attractive genes. After reading my points. Is it unethical to catch your own fish for food when it is needed for evolution?
