I wouldn’t feed them to the killer whales.
I don’t think there’s much meat on eco-freak environmentalists, though they could do the killer whales good in terms of fibre.
If there was a way to get that whale pod to go after the Sea Shepherd craft and gobble up the occupants, that would be better. Imagine what “Whale Wars” would look like if the pod trashed their high-tech tri-hull MV Brigitte Bardot and gobbled the occupants in a Sea Shepherd feeding frenzy? Now, that IS entertainment!
