"The greatness of a nation and its moral progress can be judged by the way its animals are treated." -Mahatma Gandhi. Lots of scientists claim that for them to achieve and reach their goals through the ladder of success for the humanity they have to use animals as test subjects. As a matter of fact, animals have their rights by lots of associations who defend to get them their freedom and provide a suitable environment. So, they should concern and should not involve these poor creatures as part of their scientific experiments. The following reasons will show why animals should not be used as test subjects.
The most significant reason why animals should not be used as test subjects is because it will cause an imbalance in the ecosystem. Specifically, whenever scientists use animals in their test or experiments, it actually threat and increases the chance for species to extinct after a short period of time. According to Francis S. Collins in "Experiments On Animals", every year more than 100 million animal such as mice, cats, dogs, and rabbits are killed in U.S

In specific, it is a waste of time and money. For example, scientists spend billions of their country's financial budget over machines, scientific equipment , new techniques and chemical items to examine these tools on animals. Sometimes these experiments fail and they just get rid of all the supplies they have bought. Also, by saying it is a waste of time it means that some animals remain under the process of trying a new chemical training could take a long time to see the result accurately. In addition, some animals immediately die while scientists wait for the chemical material to react and effect on the animal. According to "Wasteful Animal Testing", the US drug industry monopolize $50 billion per year in scientific researches, but the approval rate of these drugs has not changed in 50
