Animal experiments are can be harmful for the animal as an entity, while these activities can beneficial for extended knowledge. While there is a disadvantage of animal experiments, I would argue that it can be justified with several considerations and proposed some alternatives.
Experimentation animals are usually done by profesional team who expert in that field. These come with a purposes to gain extensive knowledge, even to identified new things that may arise in the future. It becomes really important to solve scientific problem or in people daily lifes. The result form the experiments are being such an investment for the future as it provides long term-solutions. Because of that concern, there will be a tight protocol to do so, which ensure the animals well-being. For example, rat that chosen to be used in the experiment will have an anasthesy before the experiment started.
Furthermore, there are several alternatives that I can proposed to ensure the quality of animal. First, laboratory need to research about better anasthesy to let the animal will feel less harm. Secondly, animal that used in the experiments preferebly the elder one, because their life is not longer than the others. Finally, the certain stakeholder should make a legal approach to ensure the animal experiments run in an appropriate way, so it is strictly can be done by expert.
In conclusion, animal experiments can be harmful if it done without no protocol, within the advantages and several proposed alternatives I believe it will be more beneficial and can be justified with animal well-being consideration.
