1. Animals are good models for studying human diseases. Animals share many similarities with humans, including similar organs, tissues, and cells. This makes them good models for studying human diseases and for testing potential treatments.
2. Animals can be used to study the effects of toxic substances. Animals can be exposed to toxic substances to see how they affect their health. This information can then be used to set safety standards for humans.
3. Animals can be used to develop new drugs and treatments. Animals can be used to test new drugs and treatments before they are given to humans. This helps to ensure that the drugs and treatments are safe and effective.
4. Animals can be used to study behavior and cognition. Animals can be used to study how they learn, remember, and interact with their environment. This information can help us to understand human behavior and cognition.
5. Animals can be used to develop new technologies. Animals can be used to test new technologies, such as surgical techniques and medical devices. This helps to ensure that the technologies are safe and effective before they are used on humans.
Scientists use animals for testing because it is necessary to advance scientific knowledge and to develop new ways to treat diseases. However, scientists also recognize the importance of animal welfare and take steps to minimize the pain and suffering of animals used in research.
