I think that Mammals shouldn't be kept in captivity. The reasons why are because,Mammals need to be in their natural habitat so they can bond with their families and learn to protect eachother from any other dangerous mammals in the ocean. Mammals shouldn't be kept in captivity because the human interaction in captivity increases the risk of transmitting diseases to the animals.Mammals perform tricks that can be dangerous to us humans and are out of their natural life in the ocean. The best way to learn about these mammals is observe them in their natural habitat instead of learning about them in captivity because they can become dangerous to humans when they interact with eachother.I think dolphins are being in an inhumane way. The reason why is because Dolphins are use to hunting for their food in the ocean and they are loosing their predatory sence.They are in a small tank, wich means that they don't have much freedom to swim around. These dolphins are being fed fast food like french fries, chips, and food that is not supposed to be fed to animals and it can cause instential injuries,poisoning and they can even die for eating that type of foods.I believe that animals should not be held in captivity at all.
