Is animal testing justified to save human lives?

Daily Debate #561: "Is animal testing justified to save human lives?". You are arguing AGAINST the motion. Your opponent: Carl Sagan.

No it is not

You're saying animal testing isn't justified? Then you're willing to let people die from untested drugs. Show me how you approve human suffering when we have alternatives that work—or admit the math is brutal but necessary.

animal testing is literally testing on innocent animals and no human should not die from untested drugs but rather test on criminals like rapists who deserve a punishment and we can also test the drugs. why test on poor sninals who have done nothing towards you?

You're arguing for testing on prisoners—that's exactly where this collapses. Who decides who's "criminal enough"? History shows governments use that power to test on political prisoners, the mentally ill, the poor. Nazi doctors said the same thing about their victims. Once you build that machinery, you can't control who goes in it. Animals can't lobby Congress to stop the abuse.
