Many on here believe that a human being is infinitely more valuable than any animal. In that case, I would ask people to consider the following hypothetical.
Suppose a multi-billionaire developed an extremely rare form of cancer that will end her life in 2 years – so rare, in fact, that this particular disease will never affect anyone else. Luckily for her, she has enough money to fund a research program to find a cure, but the program would involve performing extremely painful and fatal experiments on over 10 billion mammals (cats, dogs, squirrels, whales, monkeys, you name it). If an animal rights group were able to block this research program, thereby dooming the multi-billionaire to her fate, would that be wrong? I believe it would be morally abhorrent to sacrifice over 10 billion mammals to the save the life of one human, but that seems to be a necessary (absurd!) consequence of the view that human life has infinite value. What say you?
