Another article on the problem. I only quoted a few paragraphs, read the rest of the article for more information. (BTW, whoever suggested that if the bee population collapses the entire flowering ecosystem collapses with it is just FEAR MONGERING. Bees are not the only insect or method of pollination.)

The plight of the honeybee

Are honeybees becoming an endangered species? Their numbers have been declining drastically across North America, more so in the United States than in Canada, but how serious is the problem?

The latest phenomenon threatening honeybees is known as "colony collapse disorder," referred to as CCD by scientists, beekeepers and farmers. It has not yet been detected in Canada — perhaps because spring results are not yet in — but a Canadian authority on bees says CCD in the United States is "an absolute catastrophe."

Dr. Peter Kevan, an associate professor of environmental biology at Guelph University in Ontario, says the cause of CCD remains a mystery. It might be caused by parasitic mites, or long cold winters, or long wet springs, or pesticides, or genetically modified crops — or stress.

"In Canada, we can be proud that Canadian beekeeping seems to be a gentler practice than in the U.S.A., especially when it comes to the major commercial operations there. Canadian beekeepers, by and large, seem to use fewer chemical and antibiotic control agents against pests and diseases than do their U.S. counterparts, and those that are used are applied more conservatively.

"Migratory beekeeping for pollination services is not so much a part of commercial beekeeping in Canada as it is in the U.S.A., and where it is practised in Canada, the moves are shorter and fewer. Nevertheless, vigilance is required. Beekeeping in Canada and the U.S.A. share too many similarities for Canadians to dismiss the problem out of hand." http://www.cbc.ca/news/background/insects/index.html
