called Colony Collapse Disorder or CCD, and it threatened California's very profitable almond industry, which is dependent on bees to pollinate the trees that the nuts grow on. And not just almonds: 130 crops in California alone depend on honey bees. Beekeepers from around the nation started loading their hives on trucks and bringing them to California to rent them out to growers.
d. What the scientists have discovered is that they really don't know very much about bees. They've found that colonies with CCD have an abundance of bacteria, viruses and a specific fungal disease, but none of these items alone can be singled out as the cause. Why should cause again be searched from the nature? Why not from human actions? In the agriculture, in order to take more harvest, hundred types of chemicals have been used to keep them from worms. And as an unintended consequence bees also have been disappearing. If they are extinct, there will not be any pollination, no pollination - no fruit, no fruit- no seed to grow the next year then.
