Playing devils Advocate why not eat humans? If we are going to eat Whales and Dolphins that are so high in mercury that it is poisoning themselves why stop others from cannibalism. Lets face it there's a new market for the Boat People?
Remember for those that say Dolphins or whales are just food swimming. How often has your food saved your life? Dolphins have recorded through out history saved man from drowning on several occasions.
Oh and for the Tuna post we don't farm tuna and we still fish for it, but many strains of Tuna are now listed on the critical endangered list? For some like Blue Fin Tuna it is more than likely too late.
One more point on the killing style used. In the old days man would charge into the jungle, heard up a family or troop of Orangutans, Gorillas or similar and slaughter most, keep the young and sell them to zoo's. If that practise was done today there would be heads rolling all over. But the Japanese think it still okay to heard an entire pod of dolphins, a extended family and slaughter them slowly one after another until the water runs red with blood.
This does not belong in the 20th century and beyond.
