Animal testing has been going on for decades all around the world. Increasingly however, more and more protests have been happening against animal testing. People from countries all over the world have started noticing and are working towards banning animal testing but not all people have this view point. This essay will be discussing the negative effects of animal testing and why it should be banned.
So first of all, what is animal testing? Animal testing is the use of animals in experiments and development products used to determine toxicity, dosing and efficiency of the tested drugs before proceeding to human clinical trials. Animal testing is used to make sure that products designed for humans do not have a negative effect on user.
Many animals are used in animal testing, some animals are mice, rats, rabbits, cats, dogs but these animals are only a small fraction of the animals used. In the United States 1.28 million animals are used for testing but this number does not include smaller rodents such as mice and rats, an estimated 100 million more mice and rats are used for testing but if you look at Canadian statistics this number increases. Approximately 3.38 million animals are used in experiments in Canada alone . Housing and experimenting on animals do not come without a cost though; the estimated cost in the United Sates alone for animal testing is over $ 136 billion dollars annually.
Although there are other options that are cheaper and more humane, animal testing continues to be wildly used. Some of these options include is the use of human cell-based toxicity screening to test drugs, chemicals, cosmetics and other products. This method replaces tests on animals such as pumping substances into animals’ stomachs and lungs and dripping chemicals into the animals’ eyes and raw skin. Another newer method invented by scientists and engineers at Harvard’s Wyss Institute is called organs-on-a-chip, Lung-on-a-chip and gut-on-a-chip. These devices contain human cells in a 3 dimensional system that copies the human organs. These chips can be used for disease research, drug testing and toxicity testing. Researchers have found that MaTek’s 3-D human skin tissue equivalent can be used as a substitute for animals when conducting burn research and cosmetic testing. All these option are available but yet they are not being used. Not only are these humane ways of testing also cheaper but they don’t take as long as to conduct as animal testing takes. If these reasons aren’t good enough to use these methods, studies have shown that animal studies do not reliably predict the human outcome , in fact 9 out of 10 drugs that appear promising in animal studies fail to receive approval in the human clinical trials.
Although there are laws set up to maintain a safe environment many work places and laboratories are unregulated because the animals they test do not fall under the laws that should protect them, some of these animals being mice and rats....
