While is undeniable that some of them keep the animals in terrible conditions the good ones have a great importance. Without zoos, our options are thin and decrease daily. It is clear for everyone that no creature is as free behind bars as it is running in the wild. However, although some zoos have a worrisome problem with maintance and infrastructure, some do a valiant job in protecting endangered species that have nowhere else to go. In other words, on one hand you have the incarceration and hunger of horrible zoos, while on the other you have the protection from harm in the good ones. Zoos are not the only option for wildlife preservation. You also have Safaris, Animal Shelters and Natural Reserve areas. Yet, such alternatives are not always possible. With increasing deforestation and hunting, bigger areas can become way harder to protect. For instance, many reserves in Africa and in the Amazon have to use highly trained armed professionals to defend the fauna. Safeguarding the wildlife is a challenge with increasing difficulties. Usually, zoos are one of the best soutions for animals that have lost almost completely their habitats. The ones that should be closed are the zoological gardens that are more like a prison than an a centre to boost the survival chances of species. Furthermore, when possible, options closer to nature and with more space should be protected by competent professionals and countries governments.
