Some people say that it is necessary to use animals for testing medicines intended for human use. Others, however, think it is cruel and unnecessary. Discuss both views and give your own opinion.

There is a belief that experiments on animals whose aim is to test medicines are crucial while others support that animals shouldn’t be used for medical research. Personally, I firmly advocate that testing medicines on animals is inhumane.
On the one hand, society can gain some medical and biological achievements when carrying out trials on creatures. Firstly, it is the experiments on animals that plays a significant role in navigating infectious diseases between human and wild species.In fact, tests on wild bats in Wuhan, China reveal why the virus is called Covid-19 and how they cause community transfer, which is the fundamental base that leads the scientists to formulate a vaccine. In addition, the distribution of testing on animals to the genetic biological field is undeniable because it provides biologists with foundations to create creatures with better physical conditions. For example, Dolly, the first sheep to be cloned from an adult somatic cell by associates of the Roslin Institute, whose life expectancy is longer than its peers is a new type of sheep .

On the other hand, testing on animals to serve the healthcare is not a humanitarian activity. Initially, the more the scientists conduct experiments on creatures, the more the animals suffer from mental and health problems. Put simply, animals will be likely to face diseases if they are confined in low-quality facilities and undergo enormous tests for a long time. Secondly, using animals for research in the medical field leads to the decrease of their population because they are poached by hunters on a large scale in order to sell to researchers working in the healthcare services. For instance, there has been a sharp decrease in the number of California sea lions due to the indiscriminate exploitation of hunters since the scientists conducted experiments on the lions and came to the conclusion that the sea lion’s brain can cure epileptic.
In conclusion,the testing on animals is said to be essential for the medical area although some individuals find it brutal to use animals for testing the medicines. Nevertheless , I strongly support that creatures shouldn’t be used for medical trials.

Errors and Improvements:

"There is a belief that experiments on animals whose aim is to test medicines are crucial while others support that animals shouldn’t be used for medical research." -> "There is a prevailing belief that experiments on animals conducted to test medicines are crucial, while others argue against the use of animals in medical research."
Explanation: The revised sentence introduces a more formal tone by using "prevailing belief" and rephrasing to specify the purpose of the experiments more precisely. It also avoids contractions for formality.
"Personally, I firmly advocate that testing medicines on animals is inhumane." -> "Personally, I strongly contend that subjecting animals to medical testing is inhumane."
Explanation: Replacing "firmly advocate" with "strongly contend" enhances the formality of expression. Additionally, the use of "subjecting animals to medical testing" is more precise and formal than "testing medicines on animals."
"it is the experiments on animals that plays a significant role" -> "experiments on animals play a significant role"
Explanation: Correcting subject-verb agreement by changing "plays" to "play" and simplifying the sentence for clarity without altering the intended meaning.
"tests on wild bats in Wuhan, China reveal why the virus is called Covid-19 and how they cause community transfer" -> "tests on wild bats in Wuhan, China reveal the origins of the Covid-19 virus and how it can be transmitted within communities."
Explanation: Clarifying the sentence by specifying that the tests reveal the origins of the virus and improving the description of community transmission.
"distribution of testing on animals to the genetic biological field is undeniable because it provides biologists with foundations to create creatures with better physical conditions." -> "integration of animal testing into the genetic biological field is undeniable as it provides biologists with the foundations to create organisms with improved physical traits."
Explanation: Substituting "distribution" with "integration" for a more accurate term and rephrasing for precision and formality.
"Dolly, the first sheep to be cloned from an adult somatic cell by associates of the Roslin Institute, whose life expectancy is longer than its peers is a new type of sheep." -> "Dolly, the first sheep cloned from an adult somatic cell by researchers at the Roslin Institute, represents a new breed with a longer life expectancy than its counterparts."
Explanation: Rearranging the sentence for better flow and specifying that Dolly represents a new breed with a longer life expectancy.
"the more the scientists conduct experiments on creatures, the more the animals suffer from mental and health problems." -> "With an increase in the number of experiments conducted by scientists on animals, there is a corresponding rise in the animals’ mental and health problems."
Explanation: Improving clarity and formality by restructuring the sentence and avoiding repetition.
"animals will be likely to face diseases if they are confined in low-quality facilities and undergo enormous tests for a long time." -> "Animals are more likely to contract diseases when confined in substandard facilities and subjected to extensive testing over an extended period."
Explanation: Enhancing formality and precision by rephrasing and specifying the conditions under which animals may contract diseases.
"using animals for research in the medical field leads to the decrease of their population" -> "utilizing animals for research in the medical field contributes to a decline in their population."
Explanation: Substituting "using" with "utilizing" for a more formal tone and improving the wording for precision.
"there has been a sharp decrease in the number of California sea lions due to the indiscriminate exploitation of hunters since the scientists conducted experiments on the lions and came to the conclusion that the sea lion’s brain can cure epileptic." -> "The population of California sea lions has sharply declined due to indiscriminate exploitation by hunters, following experiments by scientists who concluded that the sea lion’s brain has potential in treating epilepsy."
Explanation: Clarifying the cause of the population decline and improving the connection between the experiments and their conclusions.

There is a prevailing belief that experiments on animals conducted to test medicines are crucial, while others argue against the use of animals in medical research. Personally, I strongly contend that subjecting animals to medical testing is inhumane.

On one hand, experiments on animals play a significant role in medical and biological advancements. Firstly, such experiments contribute to our understanding of infectious diseases that can transfer between humans and wild species. For example, tests on wild bats in Wuhan, China, revealed the origins of the Covid-19 virus and how it can be transmitted within communities, forming the foundational knowledge that led scientists to develop a vaccine. Additionally, the integration of animal testing into the genetic biological field is undeniable, providing biologists with the foundations to create organisms with improved physical traits. Take Dolly, for instance, the first sheep cloned from an adult somatic cell by researchers at the Roslin Institute. Dolly represents a new breed with a longer life expectancy than its counterparts.

On the other hand, utilizing animals for medical research raises ethical concerns. With an increase in the number of experiments conducted by scientists on animals, there is a corresponding rise in the animals’ mental and health problems. Animals are more likely to contract diseases when confined in substandard facilities and subjected to extensive testing over an extended period. Moreover, the exploitation of animals for research purposes contributes to a decline in their population. The population of California sea lions, for instance, has sharply declined due to indiscriminate exploitation by hunters, following experiments by scientists who concluded that the sea lion’s brain has potential in treating epilepsy.

In conclusion, while some argue that testing medicines on animals is essential for medical advancements, others find it brutal and unnecessary. Nevertheless, I strongly support the view that creatures shouldn’t be used for medical trials, considering the ethical implications and the potential harm to animal populations.
