However, some estimates suggest that anywhere between 50 to 100 million animals are used for animal testing each year, and a significant number of these animals may face potential harm, injury or death during the testing process.
It's important to note that animal testing includes a wide range of procedures, from non-invasive observations and behavioral studies to more invasive techniques that may involve surgery, chemical administration or the intentional infliction of pain. While there are strict regulations and guidelines in place in many countries to ensure animal welfare and reduce the harm to animals as much as possible, there are still concerns and ongoing efforts to reduce animal testing and find alternative testing methods.
