Truth is in favor of you and me; for the truth of our enemies whom we have been serving here in the U.S.A. for over 400 years (whom we did not know to be our enemies by nature) is the truth that the Black Man must have knowledge of to be able to keep from falling into the deceiving traps that are being laid by our enemies to catch us in their way which is opposed to the way of righteous of whom we are members. ~ The Honorable Elijah Muhammad

Wild Bee Decline Threatens U.S. Crop Production | Environment
The first national study to map U.S. wild bees suggests they’re disappearing in many of the country’s most important farmlands — including California’s Central Valley, the Midwest’s corn belt and the Mississippi River valley.
If losses of these crucial pollinators continue, the new nationwide assessment indicates that farmers will face increasing costs — and that the problem may even destabilize the nation’s crop production.
The findings were published Dec. 21 in the Proceedings of the National Academy of Sciences.

Pesticides stop bumblebees from pollinating apple trees, research shows
Wild bees, crucial pollinators for many crops, are on the decline in some of the main agricultural regions of the United States, according to scientists who produced the first national map of bee populations and identified numerous trouble spots.
The researchers on Monday cited 139 counties as especially worrisome, with wild bee numbers decreasing while farmland for crops dependent on such pollinators is increasing.
The counties included agricultural regions of California such as the Central Valley, as well as the Pacific northwest, the upper midwest and Great Plains, west Texas and the southern Mississippi river valley.
US wild bee numbers decline as land is converted for biofuel - BBC News
Wild bees in the US have declined in many farming areas according to the first national effort to map their numbers.
The study suggests that between 2008 and 2013, the numbers of wild bees went down across almost a quarter of the US.
The researchers say that the conversion of land to grow corn for biofuels is a key element in the decline.
If the trend continues say the scientists, it could drive up costs and destabilise crop production.
Wild bees play an important role in pollinating many US crops and plants. It's estimated that they contribute around $3bn to the value of agriculture every year.

Beyond Honeybees: Now Wild Bees and Butterflies May Be in Trouble | WIRED
Wild bees and butterflies are out on the landscape, making them difficult to count, and a lack of historical baselines makes it challenging to detect long-term trends. Slowly but surely, though, results from field studies and anecdotal reports from experts are piling up. They don’t paint a pretty picture. Many pollinator populations seem to be dwindling.
