Section 2: Animal - Zoo 1. To what extent is the use of animals in scientific research acceptable? Should we use animals in scientific experiments? Animal 2.doc - Most scientific research has to rely on the results of animal experiments. Other alternatives, such as computer modeling, that could replace animals are very limited. Some people think that using animals in scientific experiments is immoral and cruel. - In my point of view, only animals can fulfill the requirements of scientific experiments in a real world. For example, some medical universities use dogs as a substitute to allow students to be trained in their surgical techniques. Most people understand that we cannot use humans in experiments because it may be harmful and dangerous for humans. In other laboratory experiments, scientist often use animals like rats, frogs and rabbits to observe the results because only these animals have a similar organs as humans. Therefore, we can not deny that animals contribute a lot to the development of science. - Although it seems impossible to replace animals in scientific experiments, we should not give up on these matter. Furthermore, we should try our best to reduce the use of animals in scientific experiments. In addition, we should try to reduce pain and distress of the animals during the experiments. For example, we can anaesthetize them before doing any experiments. |
