Who told you that it will be thrown away
Whale 'nads, kidney (or to be more exact the glands sitting on top of the kidney in mammals), hypothalamus, pancreas, etc used to go straight into the pharma hormone extraction business.
So this used to be not thrown away - it is about the same evolutionary distance from us as cows, but MUCH bigger volumes to feed into the same process (so even complex protein based stuff like growth factors, etc could be extracted and used in humans). Similarly, other stuff went into cosmetics, etc.
It is thrown away now as a result of conservationists efforts because using it does not pass the cost-benefit and security risk assessment in pharmaceutical companies.
Do not understand me wrong - killing endangered species when there is absolutely no need for it is a CRIME. However, once they are dead, they are dead. So wasting them in this manner only because not a single one of the pharma companies wants to see yet another GreenPeace demo in its parking is a CRIME too.
