Horses and humans. For a long time, the oligarchs and wealthy classes in every country bred, fed and maintained their equine populations. They earned a living by providing a service to the wealthy, which was transportation. Horses became specialized in certain things like fighting in a war, pulling carriages, etc... and some more than others were more highly valued and traded as workers to other companies (wealthy families and businesses)... They needed horses to do all this work so they expanded the horse population. By the 1900s, it was massive. The horses themselves were worth so much money because of the labor they provided the wealthy classes. Then the automobile was created and suddenly the wealthy didn't need the services anymore. It didn't take long for the world equine population to drop substantially never to recover.
