New resistant strains of disease could wipe out global wheat fields
Monday, May 16 201
Leading wheat experts have in the past warned that the evolving pathogen may pose an even greater threat to global wheat production than the original Ug99.
The four new mutations of Ug99 have overcome existing sources of genetic resistance developed to safeguard the world’s wheat crop.
Honey bee loss same as previous four years
WASHINGTON D.C. — Total losses from managed honey bee colonies nationwide were 30 percent from all causes for the 2010/2011 winter, according to the annual survey conducted by the U.S. Department of Agriculture (USDA) and the Apiary Inspectors of America (AIA).
This is roughly similar to total losses reported in similar surveys done in the four previous years: 34 percent for the 2009/2010 winter, 29 percent for 2008/2009; 36 percent for 2007/2008, and 32 percent for 2006/2007.
Bat Crisis Threatens U.S. Food Supply
To date, over one million bats are thought to have died from White Nose Syndrome, a condition that awakes bats early from hibernation before there is enough available food. In addition, scientists have estimated that by 2020, 33,000 to 111,000 bats could be killed annually by wind turbines in the Mid-Atlantic Highlands alone. While wind turbines provide a great source of green energy, they are not kind to certain species of migratory, tree-roosting bats.
Comment by Adamantine:
These three problems seem to be threats but I have no way of knowing if these are greater than the usual threat to food supply that the world always faces. None of the three seems to have become out of control. I hope they remain in control.
