This philosophy, popularized by thinkers like Tom Regan and Peter Singer, suggests that animals are "subjects-of-a-life" and should not be treated as property or resources. Rights advocates believe that: Animals should not be used in medical testing , regardless of the benefit to humans. The industry of factory farming should be abolished rather than reformed. Animals should not be used for entertainment , such as in circuses or zoos.

Animal welfare refers to the physical and psychological well-being of animals, encompassing their living conditions, treatment, and experiences. Animal rights, on the other hand, is a philosophical and ethical movement that advocates for the inherent rights of animals to be treated with respect, dignity, and compassion. The animal welfare and rights movement has evolved significantly over the years, with increasing public awareness and concern for animal suffering.

The tension between animal welfare and animal rights is unlikely to resolve soon, because it mirrors a deeper tension in human ethics: Is it better to do the least bad thing, or to refuse to do the bad thing at all?

As humans, we share this planet with a diverse range of species, from the majestic elephants and lions to the tiny insects and microorganisms. Animals play a vital role in maintaining the balance of ecosystems, and their well-being is intricately linked to our own. However, the way we treat animals has been a topic of debate for centuries, with many arguing that we have a moral and ethical responsibility to protect their welfare and rights.
