Were they suitable for the animals? Can animals live in artificial setting instead of their natural habitat? In your opinion, will the animals be comfortable in a zoo or in their natural habitat?

Explanation

In the zoo, the tall trees and bushes are grown abundantly. There are a lot of ponds, water reserves and artificial lakes made here and there. Fruit trees are also grown in plenty. To some extent these facilities are suitable but not sufficient.
During winter, animals are provided with heaters to provide them heat. And during summer, arrangement of coolers is made to make wild animals. life comfortable.
But, I believe, these are not appropriate, because wild animals would like to live in forest happily and not in these artificial settings. Wild animals will be far more comfortable in their natural habitat than in zoo.
