The purpose of the bees disappearing is to execute a global famine. Everyone knows economic collapses are engineered by contracting the supply of money/credit while pushing the stock market down in a short period of time. Now with advancements in technology (specifically nano-tech as shown on this site) the ability to collapse the food supply is now in they're grasp too.

Using chemtrails (probably again leveraging nano-tech, but could simply be the barium in the chemtrails instead) the bees like everything else are sprayed all day long. As the population of the bees dwindles you'll notice they never completely die out. This is the point. Using chemtrails they have struck a balance of allowing just enough bees to survive and pollinate crops year over year but at the same time with one hard day of chemtrailing the rest (say there are only 10% of the bees now remaining) would be wiped out in a week. Doing this at the proper time of the season and 90% of the crops (wheat and corn?) would fail. At the same time the futures price of all commodities would be pushed up fast resulting is a complete lack of food and if any food is found it will be sky high expensive. Also note Codex Alimentarius and other legal restrictions on farmers; specifically the GMO crops that are used. The key to the GMO crops is not the fact that they are bad for you, but the seeds the farmers get from Monsanto for that given growth cycle (year) would fail to spawn/grow intentionally, right on schedule with a complete collapse of the remaining bee population. This is the real reason for the push for GMO seeds onto farmers. It's so the rug can be pulled out from under the crop yields just in time with an escalating futures price for food based commodities and the bee die-off. Sprinkle on some weather manipulation to create a bunch of tornados in the bread basket of America and some inflation to boot and you have the worlds first completely engineered famine. There will be a day within the next 25 years that you cannot buy a loaf of bread for under $350 (inflation adjusted, equivalent price in today's dollars is about $140 I figure).
