Im ok with shark hunting because sharks dont age and are immune to disease and top of the food chain, in other words the is virtually no way for them to die. If you keep them alive they will overpopulate. Im not cruel I hate animal cruelty but this is my opinion.
Immortal? I'm not a scientist of anything but im pretty sure sharks are not immortal! It can take 2 weeks for the shark to die, it just lays on the sea bed while other animals eat away at it.... sound nice to you?
Fishing nets kill sharks, hunters kill sharks and finning kills sharks (to name a few).... Have u ever thought that they don't die of old age because they don't get chance! Also, if they don't die from disease we should be watching and learning from these magnificent animals... Cure for cancer anyone?
