Since this strange phenomenon surfaced in the fall of 06, scientists continue to scratch their heads as they try and determine what exactly is causing the deaths of so many bees. At first they thought they had identified the killer as one particular virus (the Varroa mite), but now feel this CCD (colony collapse disorder) on such a monumental scale could have many faces. Whatever the cause though, the problem effects everyone. These busy workers pollinate all of the many flowers that are responsible for all of the many fruits, vegetables, grains, legumes, nuts and seeds that make up our diets, and without natures little pollinators our diets may not consist of much more than water...
Although I have no formal education on the subject, I've had my own idea of what may be happening and finally there seems to be scientists connecting the same dots.
There has been an abundance of research detailing the health benefits of organically grown food in comparison to that of which is grown using chemical fertilizers due to the higher levels of nutrients and anutrients in organically grown food. New research is showing that this lack of nutrients in non-organic foods is not only having a negative effect on us, but appears to be detrimental to the plant itself as well. By now many people know that such anutrients such as polyphenols are extremely beneficial to our immune systems, but most people don't consider how beneficial these chemical substances may be to the plants immune (or defense) system. Research now shows that polyphenols may actually be responsible for acting as a sort of natural pesticide, but because the use of chemical fertilizers promotes over farming of land due to its ability to replenish the soil with high quantities of nitrogen, and not much else, what your left with is a very nutrient deficient earth.
This in turn causes extremely malnourished crops that are becoming increasingly more and more dependent upon toxic chemical pesticides poisoning plants and people alike, only now in my opinion it's taking its effect on our busy little bee friends, and why not? If the fruits of these plants are lacking the nutrients and anutrients that keep us healthy (and the plants), what's to say the pollen isn't nutrient deficient as well? It would only make sense then that this potentially nutrient deficient pollen would affect the world's leading pollinators... The Bees!
