Speec Should We Keep Animals in Captivity EssayIntroductionDo you know that there argon approximately a hundred million batty animals, and about twenty dollar bill thousand species that die every year? Wild animals are in great danger from nature, diseases and declination environment. The extinction of animals has become a critical problem leading us to think whether or non we should keep animals in captivity.Body DangerIn recent 50 years, nearly two thirds of the universes forest has been cut down for human industry and agriculture so that a kind of cracked animals find it harder to survive as usual. On average, in every 6 square kilometres of the forest, there are over 750 species of trees, 400 species of birds, 150 species of butterflies, 60 species of amphibians, and thousands of species of other plants. But with the disappearance of forests, more wild animals are deprived of shelters and food and die in large numbers.Next imagine that you travel to Africa with the accept to see wild animals, such as rhinos, giraffes, elephants and chimpanzees, only to find nothing but the samples displayed in the museum. underneath the display, there is the sign saying Rhinos, the world-famous animals, existed from 500 B.C to 2014 A.D., Cause of death Human poaching.

Around the world by nitty-gritty of captive propagation, humans have promoted the birth of 135 gorillas, 33 black rhino, and 123 leopards, some of which are restored to their everyday environment. Though captive propagation and reintroduction seem to work effectively and contribute to insurance against sudden or catastrophic losses of animals in the wild, I dont regard them as the major slipway to save animals.Body DisadvantagesOne of the main problems with captive propagation and reintroduction is the high cost. Capture from the wild, food, veterinary care all contribute significantly to the huge cost. Though some think this problem can be solved by fundraising. The other problem is that captive threaten animals may fail to practice their heritable traits. Animals raised in unnatural conditions where they no longer need to hunt for food, and find shelter themselves would stepwise weaken their natural instincts. For example, the animals fed from birth may never learn gathering or prey-hunting skills from their parents as they would in the wild. Generation after generation, will they reduce to home pets?ConclusionIt is a painful point that there will be no more wild animals left on the planet if the climate continues to warm up, or if humans continue poaching them. In such cases, I cant deny that captive propagation and reintroduction are effective ways to save and increase the number of endangered species. However, the animals fed and bred in artificial conditions will inevitably lose their instincts and vigour they owned in the wildness. therefrom instead of focusing on how to keep animals in captivity, we should try our best to prevent globe melting up and stop poaching with severe punishment, providing a better living condition for those innocent wild animals.Do you agree with my ideas?Or do you have better ways to settle the problem?
