Tigers, lions, giraffes and other exotic animals are rarely seen in the wild. However, the public, without simultaneously harming humans and/or animals, can see exotic animals when a zoo opens. For many, zoos are a wonderful experience, but for others they see the animals as poorly treated and not able to roam free. These people do not consider the positive sides of zoos. Zoos around the world help species that have been endangered by protecting and caring for them. Otherwise they would have become extinct and killed for their valuable fur or feathers. Zoos were created for a purpose that needed to be achieved. If there was no purpose for them they would not have been created. Zoos are necessary and if there is a need for them in this world, the place will most likely be filled without hesitation. Some zoos have not been trained properly and do not treat their animals very well. Some substandard zoos don't feed their animals enough and keep them in confined cages. Although some zoos are harmful to both animals and people, many of them are good zoos and take care of their animals better than most people take care of themselves. It's amazing to be able to see so much care and love associated with zoos. Zoos not only help endangered animals, but also help people learn to respect such extraordinary creatures. Zoos are a good attribute for society because they promote education, research, protection, conservation and perspective. Zoos have enormous value for education. Education is the process of receiving or imparting systematic instruction. Zoos provide instruction about animals and how to care for them. Zoos educate the public by showing them different animals, how they behave, how dangerous they are and how to treat them according to the article "Education - Association of Zoos and Aquariums". Zoos are an important part of education because without a public zoo some may not know how dangerous some animals are and be killed by them or even unknowingly kill an endangered species. Even without zoos, animal education would lack curiosity due to the limited presentation of examples. Children need to see to believe and without this aspect, education towards animals would suffer tremendously. A total of 175 million people have received education through zoos. They are educated about wild animals, related conservation issues, their habitats and ways they can contribute to the conservation of these animals.
