Beekeeping is a business. Much beekeeping business lies in renting hives to farmers (meaning: driving them to far away farms where the bees are then allowed to pollinate for a few days, then on to the next far away farm). Hive renting is pretty stressful to beehives, and farmers tend to use a lot of pesticides. And guess what: pesticides are pretty indiscriminate, so they hurt bees too. So yeah, this particular business has colony collapse issues. Beekeepers who produce honey, queens, and hives mostly only have to deal with varroa mites and such predators.
