Can humans survive without any other animals?

Originally Answered: Can humans survive without animals? Unfortunately not, as animals contribute to nature in ways that we will never be able to.

What animal is immortal?

To date, there's only one species that has been called 'biologically immortal': the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle.

Butterflies are often only appreciated for their beauty and not for their important role in our ecosystem. But while they certainly are fun to look at, they can actually help predict important climate changes.

Can humans live without butterflies?

We just can't predict what they'll be. If butterflies disappeared, the world would most certainly be worse off for children of all ages. But it's much worse than that. Many flowering plants are so closely linked to butterflies (and vice versa) that one cannot survive without the other.
