How many animals were killed to provide you with your soybeans?
This isn’t a facetious question. Agriculture neccesarily entails converting natural habitat to farmland. And that means killing the plants that used to live there, which means that the animals who used to live there will die. Sure, some are able to move…but they will have to displace other animals. The net result is that a certain number of animals die.
The thing is, you have as a premise that animals and plants have a different moral status. But I don’t agree. There isn’t an on/off moral status, there is a continuum. Let’s put humans on one end, and rocks on the other end. In between are chimps, dolphins, dogs, elephants, lemurs, cows, chickens, sharks, rats, ladybugs, grasshoppers, oak trees, snails, rosebushes, ferns, flatworms, mold, blue-green algae, botulism bacteria, and rhinoviruses.
At some point we start to assign these creatures a moral status. And the status gets larger and larger, depending on our aesthetics and personal beliefs. But there is no objective measure of the moral status of an organism, it is a subjective measure dreamed up by the human mind. You and I can have different moralities regarding non-human organisms that are equally valid or invalid. Doesn’t make me right, doesn’t make you wrong.
I would guess that you have an agenda here. You wish more people shared your opinion about the moral value of non-human organisms. The way to do that is to get people to examine their premises. Your OP was an attempt to do that. But you also have to examine your own premises, if only because if you understand your own premises you can argue more logically and more convincingly.
You can believe that eating animals is wrong, just because you feel eating animals is wrong. But if you understood WHY you felt that eating animals is wrong you’d perhaps do a better job. It would allow you to avoid making all kinds of mistakes.
For instance, every traditional society in the world has eaten animals, from the Eskimos to the !Kung to the Australian Aborigine. And our pre-human ancestors for millions of years ate animals. So the argument that if people really understood that meat used to be an animal they’d quit eating animals is flawed. For thousands of years people hunted, killed, butchered and ate animals, as up close and personal as you can get. It didn’t stop them from eating animals. But often those people viewed animals as having some sort of moral status. So…animals could have some sort of non-trivial moral status, but that wouldn’t mean that people shouldn’t eat them. Or that the moral status of animals must be rigorously non-contradictory. For example, there is a well known religion that believes it is moral to eat Artiodactyls but immoral to eat Perrisodactyls. Does it make sense? No, but so what? Who said it has to make sense?
