Many endangered animals now are kept in the zoo. But is it the right thing to do, or should we set them free to their natural habitat? On the one hand, zoos can protect animals from external risks, prevent them from different diseases, provide them with the necessary nutrition. Because there they are taken care of by the zoo workers. Besides, the zoo allows us to find out the habits of animals, to understand how they behave in the environment. But, on the other hand, cages in zoos restrict the freedom of animals. City noise and people's attention cause constant stress to the animals. In addition, getting used to life in cages, the animals from the zoo will never be able to exist in their habitat again. However, I think that animals should live in their natural environment, and people should do everything possible to protect the habitat of wild animals.
