ELI5:What would really happen if bees went extinct?

This was a topic that was brought up in class a girl in class said "Everything in the world would die". I don't think this is true but would like a better explanation. Thanks!

I think they're major pollenators for almost 90% of our grown food.  Without them things don't grow.  We could find another way but it would be costly, not to mention all the other plants that would die besides human food resources.  Anything like lumber and cotton would become exponentially more expensive too.
