Why not? Because without animals you wouldn't be here today.

We're only here today because animals have given us the resources to survive. From cavemen hunting for meat to bees, insects pollinating plants.

The only resource we can provide is limited breast milk, sperm and meat. But human meat is deemed socially unacceptable, sperm only exists within biological males and the biological women has a limited timespan in their life where only if the conditions are right they lactate. So no, we have no importance.

Without any feasible resources that the homo sapien race can provide, of which could provide cultivation, that in return makes humans unimportant. QED
