Most people enjoy going to the zoo and looking at the animals - but do the animals enjoy it? I think they are often unhappy and unhealthy. In my opinion it is completely wrong to keep animals in zoos.
   Animals often kept alone in small cages, where they can't move freely. Many animals become so bored &  unhappy that they die.
   When animals in zoos they are safe from hunters. Species which can't survive in wild can be bred in captivity by hunters. I would be better to save and protect the animals' in natural habitats.
   Animals can't get the exercise they need.It is also difficult to give them the same food that they eat in the wild. In zoos weather conditions may be unsuitable (e.g. too cold for lions, not cold enough for polar bears ).
   All in all, i believe that wild animals should not be kepts as pets, because every animals has the right to live freely in it's natural enviroment.
