In my opinion, I think animals shouldnt be kept in zoos because zoos dont provide good natural habitats and can put unnecessary stress on the animals. For example, zoos dont have the right facilities for hibernation animals and big animals like elephants. Zoos can be too small and limited for the elephants. Because their habitat isnt big enough to migrate, this can change their behavior and can lead to aggression. Also, zoos to people are for entertainment so animals are captured and is put into poor habitats with poor conditions and separated from other animals of their own.
