>>29 Putting restrictions on categorizing life is wrong, then, according to what you said there. A bit hypocritical, don't you think? Saying that humans are the most important and are worth the breeding and sacrifice of other animals in itself is a categorization equal to saying they're on the same level as any other animal is.
Why would saying that ants are on the same level as humans not end well?
Why should science achieve great things through misdeeds? We seem to be living fine as we are. Why do animals need to be bred to be killed for the sake of science? If it's for the sake of science, why don't we just breed and kill humans to dissect as their systems are closer? After all, that would be the best and most logical thing to do for the sake of advancing the fields of surgery, medicine, etc; the only thing stopping science from going that route is morals.
So if science has morals that get in the way of its logic, why can't I, myself, have morals which differ than yours? Why are my morals "not going to end well" just because they're different? Morals and categorizations certainly do have a place in this debate.
How far do you want science to go in the first place, and what do you think dissecting animals actually does in the true field of science? There are many uses, yes, and most of the dissections are done after experiments on various things to see the internal effects. Blatant dissection that we think of is usually done to study anatomy, but we already know the anatomy of most animals.
Do you agree with dissection in schools? Where millions of animals are killed every year so students (most of which have no intention of going on to a medical school) can cut them apart to learn when there are plenty of virtual alternatives?
Also, to those of you who are trying to say they live a nice life and are then humanely killed, do you understand what you're even saying?
Gaseous poisons may corrode their throats/lungs, so they are rarely used. They can't shoot the animal in the head (which is the fastest humane way to kill them) or else it will damage the brain. They can't euthanize them with shots (the way your dog or pet would be put down) because it is extremely expensive to do, and dissection animals aren't worth the cost or the effort to stick a needle in each and every one of them. Most of them are suffocated or electrocuted in large batches; neither of those are pleasant ways to go for any creature.
And I'm sorry, but again, not all of us have the money to eat freerange even on occasion. Even if you do eat freerange, it won't lessen the number of animals being killed already enmass for food. It will just increase the amount being thrown out at grocery stores unless you get some huge, majority movement boycotting slaughterhouse meat (which again, won't happen because a lot of people can't afford freerange meat nor "organic" food products).
