Alternatives To Animal Testing
Many animal rights organizations promote alternatives to animal testing in the development of products for humans. Animal testing is used to make sure products like cosmetics, household cleaners, foods, and drinks are safe and non-irritating for use by humans. Alternatives to animal testing are getting used more often nowadays. here are some cruelty-free ways to test products:
- Human Volunteers. For some testing that is unlikely to be too risky, humans can volunteer. Unlike animals, humans can give informed consent to have products tested on them. Therefore, the human volunteer alternative to animal testing is considered more ethical than using helpless animals.
- Cell Cultures. In vitro (in test tube) alternatives to animal testing require human cell cultures to be grown. These cultures are real human cells that are grown on purpose to be tested for irritation and toxicity of products. Use these cells, and nobody gets hurt, human nor animal. Products are put onto the cells, and the cell's reaction is watched closely. This testing shows how a human body would likely react to the test substances. If scientists require information about a skin product, skin cells are used in the testing. If information about effects on the liver is wanted, then liver cells are used.
- Computer Models. Computer models are sophisticated alternatives to animal testing. Computers are programmed with information about how cells react to various chemicals. Then, a simulation of a new product's effects on human cells is run. This alternative to animal testing uses computer analysis to predict actual biological reactions.
