Nowadays animal experiments are widely used to develop new medicines and to test the safety of other products. Some people argue that these experiments should be banned because it is morally wrong to cause animals to suffer, while others are in favour of them because of their benefits to humanity. Discuss both views and give your own opinion.

Nowadays, in order to test the effectiveness of medical products before human use, a large number of animal experimentation is implemented.
Although
these experiments bring humans many benefits, I believe that scientists should emphasize more on ethical aspects and find alternative methods for drug testing. In consideration of the biomedical aspect, there might be certain reasons why the researchers still do animal experiments.
First
, they are crucial for scientists’ improved understanding of human biology and health.
For example
, by studying model organisms, people have a clear understanding of the mechanism of the diseases.
Therefore
, they can develop new treatments,
such
as organ transplantation or stem cell.
Furthermore
, experiments involving
animals
are required for developing new medicines. Specifically, before being approved by the authority and launching, the drugs must be tested for their toxicity as well as effectiveness through conducting these trials.
On the other hand
, testing on
animals
is believed to be a cruel, unethical, and pointless action.
First
, no matter how closely related the creatures are, their genome and physiological characteristics are still different from those of humans. To be more detailed, the pharmacokinetics and pharmacodynamics of drugs are not similar between individuals, so the medicines passing tests in
animals
may fail in the following clinical trials.
Furthermore
, there are alternative tests to qualify drugs.
For example
, scientists can alternative methods,
such
as in vitro model, to test medicine which provides faster and more accurate results.
Last
but not least, activists often argue that humans have no right to subject
animals
to trauma. In conclusion, it seems to me that it would be wrong to ban testing on
animals
for vital medical research until equally effective alternatives have been developed

Include an introduction and conclusion

A conclusion is essential for IELTS writing task 2. It is more important than most people realise. You will be penalised for missing a conclusion in your IELTS essay.

The easiest paragraph to write in an essay is the conclusion paragraph. This is because the paragraph mostly contains information that has already been presented in the essay – it is just the repetition of some information written in the introduction paragraph and supporting paragraphs.

The conclusion paragraph only has 3 sentences:

  • Summary
  • Restatement of thesis
  • Prediction or recommendation

Example:

To summarize, a robotic teacher does not have the necessary disciple to properly give instructions to students and actually works to retard the ability of a student to comprehend new lessons. Therefore, it is clear that the idea of running a classroom completely by a machine cannot be supported. After thorough analysis on this subject, it is predicted that the adverse effects of the debate over technology-driven teaching will always be greater than the positive effects, and because of this, classroom teachers will never be substituted for technology.

Start your conclusion with a linking phrase. Here are some examples:

  • In conclusion
  • To conclude
  • To summarize
  • Finally
  • In a nutshell
  • In general
