At the moment there is no risk of that happening any time soon.
Industrial beekeeping techniques (like splitting hives during the off-season, industrial production of queens, etc,...) are capable of replacing all the lost colonies on a yearly basis. It is however driving up the price of pollination.
And ofcourse, if the problem would turn worse, a time will come when we can't keep up with the rate of bees dying off, at which time things will become dire indeed.
