How would the world be without Monarch Butterflies?

Yes, I'm sure it could, but butterflies are beautiful and I hope we never have to find out. In the world's history, literally millions of species have probably become extinct. This does include many insects, and they have all played a role in the food chain somewhere. Still, Einstein once made a statement that if the world lost all of its bees, humanity most likely wouldn't survive for more than a few years. Again, I hope that's something we never have to find out!
