Our bees today are very threatened by multiple causes.

In a test with a house telephone, which was was put next to a bee hive, people noticed that within a single day no bee had returned. Unlike us, insects don't have bones which at least protect a bit from electronic emissions / frequencies. Many mobile phones come with a warning not to hold the phone near your head. Now imagine how bees feel nowadays while there is radio, GPS, WLAN and other frequencies in use filling the room everywhere. It's getting even worse with the current expansion to 5G, which radiates with about 8 times the power and is supposed to get a sending station every 100 meters. We have to stop tihs and be fine with a bit less mobile internet speed, which is barely noticeable anyway. Both for the sake of our own health, as well for that of the bees. So far already 5% of the population is supposed to have found a relation between their sleep problems, beeping sounds in their head, as well as headaches and emission reaching their homes.

On the other hand bees are threatened by pesticides, so basically plant poison. Many bee keepers already announced years ago that over 70% of their bees are gone. Possibly only those bee keppers are still left over who work in areas with lower emission and around plants with less poison, like around BIO / ecological fields or woods.
