Over the course of three years, the research team evaluated 382 different sites in 40 states, and mulled data from over 73,000 museum records. They determined that bumblebees are needed to pollinate various fruits and vegetables, and that they accomplish this task in a very unique way.
"The 50 species (of bumblebees) in the United States are traditionally associated with prairies and with high alpine vegetations," said Cameron. "Just as important -- they land on a flower and they have this behavior called buzz pollination that enables them to cause pollen to fly off the flower."
In other words, without bumblebees and the special way in which they pollinate, entire segments of agriculture are threatened with extinction. Like honeybees ( link to www.reuters.com), bumblebees are vital in order to grow food. Without them, humanity will starve to death.
Misleadingly, many experts largely blame various pathogens, fungi and viruses for the die-offs of these pollinators, while giving only a brief mention -- if any at all -- to the toxic pesticides and herbicides that are increasingly being linked to things like colony collapse disorder (CCD), the name given to the mass bee die-off phenomenon. A recently leaked report, for instance, has revealed that a popular Bayer herbicide is responsible for killing off bees ( http://www.naturalnews.com/030921_EPA_pesticides.html).
