Writing Academic Task 2 Band 6.0 Example

Some folks have debated that animal experiments should be banned because of their negative side of the environment. However, others believe that though it is a complex ethical issue, the experimentation on animals can be beneficial for scientific reasons. In this essay, I will give the reasons why it can be justified and I will also discuss whether alternatives can be used.

Animal experiments may be justified when researchers need to understand how a new medicine affects a whole living body. A treatment that appears safe in a cell sample may cause unexpected effects in organs or interact with other systems. Carefully controlled animal studies can therefore provide useful evidence before a medicine is tested on people, and this may help prevent serious harm. They have also contributed to medical knowledge and the development of treatments.

Nevertheless, this does not mean that animals should be used whenever it is convenient. They can experience pain and distress, so experiments should only take place when the expected benefit is important and no suitable alternative exists. Governments and research institutions should require ethical review, use the smallest number of animals possible, and provide humane care. Cosmetic testing, for example, is difficult to defend when it is not essential for protecting human health.

There are several alternatives. Scientists can use human cells and tissue in laboratory tests, as well as computer models to predict how substances may behave. Some medicines can also be studied with adult volunteers after initial safety checks. These approaches can reduce animal use and are sometimes more relevant to humans. However, they cannot yet reproduce every interaction within a complete living organism, so they may not replace all animal studies.

In conclusion, animal experimentation can be justified in limited cases when it is necessary, carefully regulated, and likely to produce significant medical benefits. At the same time, alternatives should be used wherever possible, and animal testing should be reduced as technology improves.
