in depends on the quality of life, the greater the purpose, the greater the overall the greater the quality.

why do we eat cows but not dogs?
cows are heavy and healthy, they are herbivores, most herbivores are meaty and tasty for carnivores, that is why carnivores likes them. i think we don't eat dogs since it can have more diseases as it eats everything it eats.

We kill spiders but not other human beings?
we kill spider since they have less purpose and a far more dangerous, we value human life since it has greater purpose, greater use.

But what greater use are we? I don't agree with this. What makes us better or think so? I think we think where better because the other animals cant disagree with us.

we rule the world, we make things better than former their selves, we expand our power faster than any animals, we can surpass any ability that animals have.

So the fact that we are smarter then other animals makes us better? If a person who has the IQ of 50 can sit in a chair an enjoy the breeze across his face, then that life is valuable, same for an animal.

animals are valuable because they use anything they have, they became valuable but compare to humans they are less valuable, humans loss their value if they can't use anything they have or they limit themselves, but in present time, i think humans can't survive if they can't use what they have so they have no choice but to use it even the least they can at least they contribute, even that least is a great contribution indeed, no one hires a worker if their work is not enough.

I have to agree with you. its like kill or be killed... but my originall intention for this argument was.. why do we kill cows and not dogs.. and one user had said cows are not self aware and have more meat so what do you think?>

Specism is about why do we eat cows but not dogs. That kind of thing. We kill spiders but not other human beings. I beilive its because we have compassion toward others like us. Thats how racism can start, or any form of prejudice. What are other thoughts?

Question: If Eating meat makes us "Speciests", then where does this put the hawk which eats other birds? Is anyone willing to call a lion a "Speciest" for eating a zebra?
