In the heart of the lush forest, there lived a woman named Ava. She was known far and wide for her unique ability to communicate with animals, a gift passed down through her family for generations. Ava's home was a secluded cabin on the edge of a clearing, where she spent her days tending to a variety of creatures, from the majestic eagles soaring above to the rabbits hopping through her garden.

This seems radical to the average person. What about a mosquito? A rat in your kitchen? Does a chicken have the right to life equal to a human child? Rights theory struggles with "conflict cases" (e.g., a lion about to eat you—do you violate its right to life to save your own?).

In contrast to welfare, the animal rights paradigm asserts that animals possess inherent value independent of their usefulness to humans. The modern animal rights movement is most closely associated with two philosophical pillars: Tom Regan’s deontological rights theory and Peter Singer’s utilitarian argument for animal liberation (though Singer himself rejects the language of "rights," his work is foundational to the movement).
