Animals are used in biomedical research for everything from basic understanding and experimenting to pharmaceutical and vaccine development. Unfortunately, it is getting more and more terrible for them to bear with the bleak conditions in laboratories. Therefore, we should seek other methods rather than abusing animals in the science lab.
Besides several advantages of animaltest such as biology lessons, medical training, drug or cosmetic trials, it seems immoral when we finish experimenting and leave them with chemical poisons, starvation, isolation, and even brain-damaged. Additionally, the laboratories’ conditions are ghastly with full of cages sometimes stacking onto others. Consequently, a number of kinds of animals that are not able to stand become stressed and harm themselves. For instance, monkeys and white rats arefrequently abused in laboratories because of their shared genes with humans. Animal experimenters conduct several drug or cosmetic trials on them, some undergo a painful procedure, so they hit their heads on their cages. More seriously, mice, cats, dogs or rabbits cannot virtually help themselves alive. Furthermore, promising experimental vaccines do not approve that they will be successful to humankind. Also, new medicinetested safely go on to fail in human clinical trials.
Therefore, non-animal methods are actionable steps that we can attempt to achieve. These days, biological advancements can contribute to experimenting, in particular, cells technology. With a tiny model of cells cultivated in the test tube, scientists can fully develop it and make use of it fornumerous purposes: vaccine production and drug development. Healthy and diseased tissues donated from human volunteers can provide a various way of studying human biology and disease than animal testing. Human tissue can be granted from surgery, for example, biopsies, cosmetic surgery and transplants.
In conclusion, it is not worth testing vaccines, medicines or cosmetics on animals because they have to suffer physically and mentally damaged. Most importantly, satisfactory results do not mean safety for humans. Therefore, replacing animals used in testing will improve the quality as well as the humanity of science. Non-animal methods are often cheaper, quicker and more effective.
