【正确答案】 Animal protection is a big issue now, especially in developed countries. People are right to believe that wild animals, as a natural part of the biological world, should be protected. But some animal rights advocates, however, have gone too far. They sabotage medical facilities in hospitals or send bomb scare to medical schools where experiments are carried out on animals. These incidents make us wonder if it is right to use animals In medico! experiments. In my opinion, these extremists are wrong. First, animals don''t have the same mental frame as mankind. Human beings are the only animals that have sophisticated perceptions of love, fear, shame, esteem, etc. It is argued that some animals have some of these perceptions but the degree is simply not comparable with what human have. Secondly, nearly all animals used in medical experiments are specially raised in sophisticated farms to safeguard the quality of experiment. Most common ones are mice, guinea pigs, rabbits and, occasionally, dogs and monkeys. None of these are wild animals. Using them in experiments is not different from slaughtering chickens, pigs, sheep and cows, Finally, all the experiments have one common goal — to improve the life of mankind. Thanks to the development of medical science, life expectancy in many countries has more than doubled in the last 150 years, part as which is attributed to using animals to test new drugs and new techniques. Therefore, to benefit everyone in the world, we will continue using animals in experiments and the issue of animal protection is simply irrelevant.
