31 Percent Of U.S. Honey Bees Were Wiped Out This Year
– Who Will Pollinate Our Crops?

This past winter was one of the worst on record for bees. In the U.S., beekeepers lost 31 percent of their colonies, compared to a loss of 21 percent the previous winter. In Canada, the Canadian Honey Council reports an annual loss of 35 percent of honey bee colonies in the last three years. In Britain, the Bee Farmers’ Association says its members lost roughly half their colonies over the winter.
“- It has been absolutely catastrophic,” said Margaret Ginman, who is general secretary of the Bee Farmers’ Association. “This has been one of the worst years in living memory.”
If bees keep dying off at this rate, we are going to be facing a horrific agricultural crisis very rapidly in the United States. Last winter, 31 percent of all U.S. bee colonies were wiped out. The year before that it was 21 percent. These colony losses are being described as “catastrophic” by those in the industry, and nobody is quite sure how to fix the problem.
Some are blaming the bee deaths on pesticides, others are blaming parasites and others are blaming cell phones. But no matter what is causing these deaths, if it doesn’t stop we will all soon notice the effects at the supermarket. Bees pollinate about a hundred different crops in the United States, and if the bees disappear nobody is quite sure how we will be able to continue to grow many of those crops.
This emerging crisis does not get a lot of attention from the mainstream media, but if we continue to lose 30 percent of our bees every year it is going to have a cataclysmic effect on our food supply.
The frightening thing is that the bee deaths appear to be accelerating and they appear to be even worse in the UK and Canada…
Scientists have been scrambling to figure out what is causing this, and one study that was recently conducted by researchers at the University of Maryland and the U.S. Department of Agriculture may have some answers…
The study, published July 24 in the online journal PLOS ONE, is the first analysis of real-world conditions encountered by honey bees as their hives pollinate a wide range of crops, from apples to watermelons.
The researchers collected pollen from honey bee hives in fields from Delaware to Maine. They analyzed the samples to find out which flowering plants were the bees’ main pollen sources and what agricultural chemicals were commingled with the pollen.
The researchers fed the pesticide-laden pollen samples to healthy bees, which were then tested for their ability to resist infection with Nosema ceranae – a parasite of adult honey bees that has been linked to a lethal phenomenon known as colony collapse disorder.[...]
