Why Is Animal Testing Necessary

Animal Testing: Is it Really Necessary? Every year more than 100 millions animals die due to animal testing, but many medical breakthroughs that have been discovered through animal experimentation include penicillin, blood transfusions, insulin, and many others. Which should we value above the other? Some simply see black and white to this problem, which one is right and which one is wrong. But others see shades of gray, as to some attributes of one side are okay, while the other one is not. Animal testing should be allowed if experimentation is for something that benefits society, but should not be used for pure selfish curiosity, or for reasons that count to others as needed experiments when they could have just simplify used other methods.
For example, open heart surgery would not be possible today if Richard Lower did not do blood transfusions on dogs in 1666. Animals do not always guarantee that the process will work or be safe for humans, but they are good candidates for the job. Their bodies of animals, and our bodies are alike in certain ways. Also, animals are pivotal to vaccine research because vaccines cannot be developed by tissue culture alone. The vaccines are used to control infections over the entire body, hence the reluctance to use tissue cultures. Animals are almost needed for medical experimentation, and should therefore be allowed. However, there are some animal testing methods that can be excluded. Using animals in classrooms for dissections, and other purposes are not necessary. Other teaching methods can be used before using actual animal corpses, and feces. Teachers could use 3-D diagrams, or skip the whole hands-on experience. If the school felt the process absolutely needed, they could get animals that were already dead, even though it would be difficult. The point is that this is one method that our world could go
