Step-by-step explanation:
Dr. Singer's approach to determining the rights of non-human animals is based on utilitarianism, a moral theory that focuses on maximizing overall happiness and minimizing overall suffering.
Singer argues that all sentient beings, including non-human animals, have the capacity to experience pleasure and pain, and therefore deserve moral consideration. He believes that the interests and welfare of non-human animals should be taken into account when making ethical decisions.
For example, Singer argues that using animals for scientific research should be allowed only if it benefits both human and animal welfare and if alternative methods are not available. He also advocates for implementing regulations and guidelines to ensure the humane treatment of animals used in research.
Singer's approach emphasizes the importance of considering the well-being of non-human animals and recognizing their rights to be free from unnecessary suffering.
