Our desires are simply more grist for evolution’s mill, no different from a change in the weather: a peril for some species, an opportunity for others. Our grammar might teach us to divide the world into active subjects and passive objects, but in a coevolutionary relationship every subject is also an object, every object a subject. That’s why it makes just as much sense to think of agriculture as something the grasses did to people as a way to conquer the trees.
