Has a reason and solution for the myseterious dying bees of the world been found yet?

No but i saw a farmer who's bees have all died out of 1000 on 150 are alive.The food is going up so high and now they say you can only buy 1 bag of rice as people are stocking up on food as with out bee's many foods will not be around' and it's scary.i have never seen anything this worrisome ever nor will i see something like this that hits all humans vegetarians and non alike.
