In the 19th century animals led notable advances in neurophysiology and had an increase of the amount of animal experiments. In 1970 over 5.5 million animals were used for experiments and they provided great benefits for humans. In the 19th century a scientist names Francios Magendie led notable advances in neurophysiology. All his experiments carried out without anesthesia during his experiments ("Animal Experimentation"). This shows that even though the united states are using 100 million animals each year. Animal experiments benefits humans with new cures and new treatments. A large expansion reflected a growing medical field. Vitamins, hormones, polo vaccines, cancer treatment, modern advances in immunology, and surgical …show more content…
No right to use animals as disable objects. Animal testing violates animal basic rights, and experiments conducting on them, scientists and researchers should let animals live in peace ("Animal Testing"). This shows that even though animal testing saves human, the animals can feel the pain and suffering and they don’t want to be tested on. 25 million mammals are used in the United States for research. Rodents, rats, and mice, make up 90% of animal testing. Cats and Dogs 2% and nonhuman primates 1% ("Rose"). This shows that even the animals that we love and keep as pets are take used as animal testing. Millions of animals are used each year for animal testing. As you walk into a laboratory, you can see the rows of cages holding animals. Their bodies are burned, scarred, and blood pouring of their noses ("Animal Testing"). This shows that they can feel pain, suffer, and not cared for. As soon they get to the laboratory, it's not what they expect. They are treated like they are not alive. Critics say that it's no right to use animals as disable objects 25 million mammals are used in the united states for animal testing. Millions of animals are killed each year and they are put in pain. Critics say "We can do better.... Its time to let go of the method of the past and embrace 21st century science" ("Animal …show more content…
Animals experimentations have been used for years to know if chemicals are safe for human use; some people say it's right to use animals because they don't feel pain like humans do, but other people say it's cruel and can be replaced by more humane practices. This shows how animals are treated, not good, some people care about animals lives. Since the 1800s and 1900s animal testing was right, finding out new technology. Now in present day there's more argues about it, killing about 100 million animals each year and spending 12 billion to 14.5 billion each year for animal experiments. The good things about animal testing, it's saving human lives and giving new knowledge and more information about cures and treatments for humans. Animal testing helps human survive, but when one person survives that's killing another animal, the more we save the les animals there going to be and there's species are going to be extinct. How many animals are going be killed to know there's going to be no more animals to test on, how many animal are going to be used until they go
