so we're going to be dissecting

Thats called animal cruelty. Which I am sure you know is illegal.

 

They would be alive, yes, but only until a few years later when they'd be slaughtered for food because a large amount of people approve of eating meat.

 

I've dissected a dead human body once.

I accidentally entered a college course once and...

dissecting the body was the first thing they did.

 

My heart bleeds purple piss for them.

 

Why waste good bacon

 

Not if they're sedated in a certain way, I imagine.

 

Could you provide some proof of this? I've never heard about this before and doing a search gives me results of universities doing it as research. And even then the reports I skimmed seemed rather thorough as if they were trying to minimize how often that needs to be done. As far as I can tell you made that up on the spot to invoke a reaction. I can't find a case of a live dissection being done as a routine class project.

As for the ones killed for the annual class projects. You don't see pigs dying out do you? Pigs can reproduce at an alarming rate. Their pregnancy length is a bit shy of four months and then they give birth to a litter, by those two factors a pig reproduction yield is about 25 times that of a human. And since pig products are used so commonly they have almost no risk of going extinct. After all, killing all of your livestock is bad for business.
