Answer:
we must abolish all medical research that inflicts pain on non-human animals.
Step-by-step explanation:
In his book Case for Animals Liberation, Tom Regan contends that any systemic oppression of creatures is ethically reprehensible. Animals are used for feeding, killing, traps, testing, teaching, and investigation, according to Regan. Humans as well as nonhumans, according to Regan, are both constituents of life with equal intrinsic value.
He thinks that humans as well as nonhumans must be respected similarly but without distinction, and that nonhumans should not be subjected to any societal practises that damage or injure them.
