New species can be put at danger every day and, worst of all, some species don’t exist in the wild anymore, only in captivity. Education is another focus area of a zoo, through raising awareness of animal diversity located in different points of the globe. Not everyone has the chance to travel to a specific country to see its native animals. Seeing these animals live and in colour can really put things in perspective, spike public interest on these topics, and possibly even gain public appreciation towards wildlife conservation.

Lastly, the scientific research that takes place in zoos is fundamental to obtain knowledge about animal behaviour, nutrition requirements, and reproduction cycles. This way, the staff can handle the animals properly, both in captivity and in the wild. Also, these scientific researches can give precious information about wildlife conservation.
