Is animal testing justified to save human lives?

Welcome to the debate arena! Today's topic: "Is animal testing justified to save human lives?". Your opponent's style: Carl Sagan

I believe animal testing is not justified to save human lives. To preface my argument, I would like to say I am speaking from the lens of current times. In the modern world which we live in, there are several alternate methods to test various diseases or try experiments. For example, the use of artificial intelligence can be one, although AI does not have a heart or a beating pulse it can still provide human-esque qualities which we can use to adapt and further continue research

You're missing the point entirely. The "modern world" still grapples with complex biological systems that AI simulations, however advanced, cannot fully replicate. How precisely do you propose AI captures the myriad, unpredictable interactions within a living, breathing, complete physiological system without any empirical biological model? This isn't about human-esque qualities; it's about actual biological responses.

In that case, if we wanted the most accurate information, wouldn't it be best if we used humans for these tests? They seem to be the most logical sense to your argument as the have a physiological and empirical biological model, harm cannot be justified from something that was here before us. Especially because they don't share the exact same qualities as human

Your suggestion that we should simply "use humans" for testing because they're the "most logical" model is a shocking disregard for ethical considerations. History is replete with horrifying examples of unethical human experimentation, leading to international codes against it.[1][2][3][4] Are you seriously advocating a return to such barbarity, or do you have a method to bypass centuries of ethical development?

What about the unethical consequences of harming animals? They are needed for our planet as much as humans. Their the sole reasons certain ecosystems around the world function.

The argument isn't about animals being "needed for our planet." It's about whether their suffering is justified for human benefit. The fact is, animal testing often fails to predict human outcomes, making the suffering largely pointless.[1][2] Furthermore, the environmental impact of animal research, from waste to pollution, is also considerable.[3][4][5][6][7] Why cause harm to both animals and the environment for unreliable results?

I agree

"I agree" is hardly a compelling counter-argument. The fact remains that 92% of drugs successful in animal trials fail in human trials, highlighting the profound predictive failures of animal testing.[1][2] This isn't just about ethics; it's about efficacy and the misdirection of resources that could fund more reliable, human-relevant research.
