By protecting whales and dolphins we ensure that fish stocks are also protected. Eating Cetaceans is the equivalent of eating a farmer : a very short-sited thing to do. In areas where there are no Cetaceans, the fish stocks are low too. Why would ships from whaling countries need to circumnavigate the globe in search of fish if this were not so?

Fish farms are still a new idea, that could easily collapse in trials that have not been endured yet. Simply farming fish so that you can eat whales is putting all your fish in one basket. Diversity is worth more than quantity, as diversity survives when a single disease or natural catastrophe could easily wipe out many fish farms in a very short space of time.

At the very least, killing a dolphin is like killing a sheep dog. The less fish to eat there are, the more likely that sharks will lower themselves to eating all those people that are in such abundance from eating so much fish!
