According to Captive animals, keeping animals in zoos costs millions of dollars while they can be spending their money on sheltering and saving animals. While zoos are spending money on keeping animals, they can always spend money on trying to save animals. So zoos are basically trying to get cash but most of their effort is going into the trash.
Zoos don’t allow animals to live the same way like they did in the wild and animals that are in zoos sometimes stay in zoos for months and even years
