Most of us don't live in the African savannah or in the jungles of South America so when we wish to take a glimpse at the world's most amazing animals we usually go to the zoo but what makes a zoo a great zoo. A great zoo treats the animals as residents rather than prisoners supplies optimal living conditions to the animals to make the activity as close to their natural habitat as possible. A great zoo also runs a conservation program to attempt to breathe animals that struggle to survive in the wild. The diversity of the animals kept by the zoo is another key element that makes a zoo great.
