What do you think about zoo?

There are many zoological gardens on our planet. People visit them to see large variety of animals, whose natural habitat is located far away. Zoos are also a great way of spending spare time on Sunday afternoon.
However, some people are unconvinced of good sides of zoo’s existence. In my opinion, there are both advantages and disadvantages of creating zoos. For example, our children can explore new species, rave about huge camelopards’ necks or funny elephants’ trunks. They can experience how much mesmerizing can be ordinary afternoon stroll with parents. Although kids like zoos, we all know that animals in zoos haven’t easy life. Mostly they have to exist in cosy cages or pens, eat one, usually insufficient or invaluable, meal. Many zoological gardens haven’t coped with the reconstruction of natural habitats of endangered species so that animals may suffer from sundry sicknesses.
However, I’m fully convinced that it is helpful to establish zoo and let endangered species increase their population in it. In my opinion, if governments order to close all the zoos, a huge number of animal beings will ineluctably die.
