Why not donate your organs just to science?
That way a omni isn't getting your organs and you're saving animals from being killed and researched on.
This I believe is the best solution so far. It solves all the issues posed by the argument for not being an organ donor, reduces suffering in itself, and provides the scientific community something they rarely get: permission to use something's body parts. I never even considered this, thanks Hedwig!
You ARE giving your organs to omni's ~ people / universities / doctors are animals too.
Body parts from cadavers won't stop animal testing. Non-human animals are alive and provide a physical response to "tests".
Giving your organs to "science" doesn't necessarily mean you'll be saving another person's life. The likelihood of donating your heart or your kidneys as an organ donor to keep someone else alive, is far greater.
Aside from being completely rude to Hedwig previously, you're now being completely naive. The first sentence is a non-sequiter, I'm hoping you knew what she meant.
No, body parts from humans won't immediately stop animal testing. The same as going vegan won't immediately stop animal cruelty. The point of it is to do that one thing that makes a small shift to a better end goal. You're doing your part for the animals.
Saving another persons life is precisely the PROBLEM, as it's almost certainly a meat eater, which results in the loss of many more animals lives. That was the dilemma.
