A zoo has no useful purpose. Do you agree or disagree?
选项
答案
Perhaps one of the most blameworthy factors that make some people raise their eyebrows to zoos and criticise that "A zoo has no useful purpose" is the exorbitant price of maintaining them. However, it is too hasty to say so, since most zoos have their significance, both educationally and scientifically. Modern zoos are designed to make learning about animals an interesting and enjoyable experience. They provide visitors with the chance to see rare creatures from many different parts of the globe, offering a valuable learning experience in an urban world. Meanwhile, most zoos provide educational programmes for a wide range of ages. A visit to a zoo provides opportunity for children to see and touch animals. For schoolchildren, many zoos conduct classes or day trips that focus on different aspects of animal biology and the impacts of humans on animal life. Modern zoos can also function as a sanctuary for endangered animals, therefore helping maintain ecosystem. An example of a successful reintroduction to the wild is a kind of Asian deer which was native to marshlands in northeast China before its habitat was destroyed more than 800 years ago. Since that time the species has been bred in zoos in China and later in Europe. In 1985 four deer were released to the wild where they are now breeding successfully. On the other hand, experts warn against placing too much reliance on zoos as biological "arks". More significantly, the number of species that zoos can protect is strictly limited. Today’s zoos are home to no more than a few thousand species. During the 21st century, zoo experts will face even harder decisions about which species they can afford to save.
