Animal Rights and the Ethics of Testing

Animal Rights and the Ethics of Testing Animals have been used as test subjects for medical experiments and other scientific investigations for hundreds of years. With the rise of the modern animal rights movement in the 1970s and 80s, however, many people began to question the ethics of using living creatures for such tests. Although animal testing remains commonplace today, public support for such practices has declined in recent years. Testing Regulations In the  United States, the  Animal Welfare Act  sets certain minimum requirements for the humane treatment of non-human animals in laboratories and other settings. It was signed into law by President Lyndon Johnson in 1966. The law, according to the U.S. Department of Agriculture, sets minimum standards of care and treatment be provided for certain animals bred for commercial sale, used in research, transported commercially, or exhibited to the public. However, anti-testing advocates rightfully claim that this law has limited enforcement power. For example, the AWA explicitly excludes from protection all rats and mice, which make up approximately 95 percent of the animals used in laboratories. To address this, a number of amendments have been passed in subsequent years. In 2016, for example, the Toxic Substances Control Act included language that encouraged the use of non-animal alternative testing methodologies. The AWA also requires institutions that perform vivisection to establish committees that are supposed to oversee and approve the use of animals, making sure that non-animal alternatives are considered. Activists counter that many of these oversight panels are ineffective or biased in favor of animal experiments. Furthermore, the AWA does not prohibit invasive procedures or the killing of the animals when the experiments are over. Estimates vary from 10 million to 100 million animals used for testing worldwide on an annual basis, but there are few sources of reliable data available. According to The Baltimore Sun, every drug test requires at least 800 animal test subjects.   The Animal Rights Movement The first law in the U.S. prohibiting the abuse of animals was enacted in 1641 in the colony of Massachusetts. It banned mistreatment of animals kept for mans use. But it wasnt until the early 1800s that people began advocating for animal rights in both the U.S. and the U.K. The first major animal welfare state-sponsored legislation in the U.S. established the Society for Prevention of Cruelty to Animals in New York in 1866. Most scholars say the modern animal rights movement began in 1975 with the publication of Animal Rights by Peter Singer, an Australian philosopher. Singer argued that animals could suffer just as humans do and therefore deserved to be treated with similar care, minimizing pain whenever possible. To treat them differently and say that experimentation on non-human animals is justified but experimentation on humans is not would be  speciesist. U.S. philosopher Tom Regan went even farther in his 1983 text The Case for Animal Rights. In it, he argued that animals were individual beings just as humans are, with emotions and intellect. In the following decades, organizations such as People for the Ethical Treatment of Animals and retailers such as The Body Shop have become strong anti-testing advocates. In 2013, the Nonhuman Rights Project, an animal rights legal organization, petitioned New York courts on behalf of four chimpanzees. The filings argued that the chimps had a legal right to personhood, and therefore deserved to be freed. The three cases were repeatedly rejected or thrown out in lower courts. In 2017, the NRO announced it would appeal to the New York State Court of Appeals. The Future of Animal Testing Animal rights activists frequently argue that ending vivisection would not end medical progress because non-animal research would continue. They point to recent developments in stem-cell technology, which some researchers say could one day replace animal tests. Other advocates also say  tissue cultures, epidemiological studies, and ethical human experimentation with fully informed consent could also find a place in a new medical or commercial testing environment.

How To Make Red Cabbage pH Paper Test Strips

How To Make Red Cabbage pH Paper Test Strips Its easy, safe, and fun to make your own pH paper test strips. This is a project that kids can do and that can be done from home, though calibrated test strips would work in a lab, too. Difficulty: Easy Time Required: 15 minutes plus drying time Heres How Cut a red cabbage (or purple) into pieces such that it will fit into a blender. Chop the cabbage, adding the minimum amount of water needed to blend it (because you want the juice as concentrated as possible). If you dont have a blender, then use a vegetable grater or chop your cabbage using a knife.Microwave the cabbage until its at the boiling point. Youll see the liquid boil or else steam rising from the cabbage. If you dont have a microwave, soak the cabbage in a small volume of boiling water or else heat the cabbage using another method.Allow the cabbage to cool (about 10 minutes).Filter the liquid from the cabbage through a filter paper or coffee filter. It should be deeply colored.Soak a filter paper or coffee filter in this liquid. Allow it to dry. Cut the dry colored paper into test strips.Use a dropper or toothpick to apply a little liquid to a test strip. The color range for acids and bases will depend on the particular plant. If you like, you can construct a chart of pH a nd colors using liquids with a known pH so that you can then test unknowns. Examples of acids include hydrochloric acid (HCl), vinegar, and lemon juice. Examples of bases include sodium or potassium hydroxide (NaOH or KOH) and baking soda solution. Another way to use your pH paper is as a color-change paper. You can draw on pH paper using a toothpick or cotton swab that has been dipped in an acid or base. Tips If you dont want colored fingers, soak only half of the filter paper with the cabbage juice, leaving the other side uncolored. Youll get less usable paper, but you will have a place to grab it.Many plants produce pigments that can be used as pH indicators. Try this project with some of the other common home and garden indicators. What You Need Red CabbageFilter Paper or Coffee FiltersBlender - optionalMicrowave - optionalDropper or Toothpicks - optional
