ELI5: What exactly is the issue with bees right now, why are people concerned about them?

Bees are *very* important in the process of pollinating plants and crops. They do it on a constant basis, as a process of living. It's the easiest form of "free labor" you can have. There's been a big issue in recent years where bees have been dropping rapidly in number, which can cause a huge dent in the farming industry and in nature itself.
