The reading passage asserts that zoos are becoming popular and advantageous for both animals and humans; however, the lecturer is skeptical about the passage, by stating that some benefits of zoos are misleading.
First of all, the lecturer argues that there are failures in captive breeding program. The reading passage explains that animals can ensure safety as they are being guarded by zoos, thereby preventing them from endangerment. In opposition to this hypothesis, the lecturer indicates that not many kinds of animals live in zoos and even much fewer endangered animals reside in zoos. Furthermore, genetic problems can occur when people try to breed limited number of animals, leading to many failures recently.
Next, the speaker claims that animals are not in natural environment, making scientists difficult to study the true features of them. The article explains that zoos provide useful sources to scientists to study animals. On the contrary, the lecturer states that animals in the nature are completely different from those in zoos. As a result, studies conducted by them would result in imprecise outcomes since the captivated and wild animals have dissimilar characteristics.
Finally, the professor does not agree with the reading that zoos offer an educational function that people are able to learn about animals. However, the lecturer points out that the large number of people simply visit zoos for entertaining purpose. Alternatively, they can learn animals with many other approaches rather than going to the zoos.
