Animal testing is something that I personally abhor but the problem is that it’s more unethical to test things on humans. If the animal species rapidly reproduces, then that’s not as much of an ethical issue but I would like to avoid testing on animals that aren’t prevalent tin the world. I guess you can say that a human life is worth more than an animal life so sacrificing an animal in order to save more human lives is necessary and a net positive. Science is not a black/white issue and although it’s cruel to experiment on animals, it’s necessary to benefit mankind.
