How much baleen do they even need for the puppets? Can't they just use beached whales for it?
Besides, that's a completely different issue. This whole mess is all about whales for eating. The main problem is that if they're hunted they can go extinct, and yet not a single conservation proposal was ever made. It's all just "there's still plenty of them anyway it's ok".
The author dared to always whine and complain about pollution and factories dumping waste because it affects the taste of fish and vegetables, but all the whale arguments are completely lame.
