AJ nailed it again.

I was sitting here trying to visualize a world where we have backyards full of plasmodial slime molds and children frolicking through the park with their pet snails on leashes. Or perhaps a trained mosquito. Or a sea urchin named "Fluffy".

How everything is assigned a "value" based on how we tend to perceive it, not necessarily on how it really is. Hence, a dog is given more heart-space than a snail. We might kill a spider by stomping on it faster than we would a kitten. We would share our bed with a puppy but not necessarily a pig (which might be just as intelligent).

And even in the human world, we "other" human beings based on what we perceive to be their value as evidenced by racism, ableism, sizism, sexism, etc.
