Why do people think that animal testing is wrong?

People often believe that animal testing is wrong due to ethical concerns regarding the treatment of animals, viewing them as sentient beings deserving of rights and protection from suffering. Critics argue that subjecting animals to experiments can cause pain, distress, and death, which they see as morally unacceptable. Additionally, there are concerns about the reliability of animal testing results, as they may not accurately predict human responses, leading to calls for alternative methods that do not involve animals. This combination of ethical, scientific, and animal welfare considerations fuels opposition to animal testing.
