Worst Drought Ever Alters #Yosemite National Park

Drought Alters Familiar Landscape In Yosemite National Park

"Where's the waterfall?"

YOSEMITE NATIONAL PARK — Yosemite National Park is bracing for its driest year on record, with visitor bureaus downplaying the allure of the park's most famous waterfall and instead touting the park as a destination for hiking, bicycling and photography.Yosemite Falls will probably go dry in June — two months earlier than usual, parks officials say. The Merced River, which powers the spectacular Nevada and Vernal falls before meandering across the Yosemite Valley floor, will probably slow to a shallow stream about the same time.

And with the drought enabling western pine bark beetles to kill large areas of forest, the park is preparing for a bad fire season."Visitors bureaus are saying they're not going to promote Yosemite Falls as much this year," said Scott Gediman, assistant superintendent for public and legislative affairs at the park. "My response: No problem. We have to be realistic." Read more

Voracious Worm Evolves to Eat Biotech Corn Engineered to Kill It

By Brandon Keim

(Wired) – One of agricultural biotechnology’s great success stories may become a cautionary tale of how short-sighted mismanagement can squander the benefits of genetic modification. 

After years of predicting it would happen — and after years of having their suggestions largely ignored by companies, farmers and regulators — scientists have documented the rapid evolution of corn root worms that are resistant to Bt corn. 

Until Bt corn was genetically altered to be poisonous to the pests, root worms used to cause billions of dollars in damage to U.S. crops. Named for the pesticidal toxin-producing Bacillus thuringiensis gene it contains, Bt corn now accounts for three-quarters of the U.S. corn crop. The vulnerability of this corn could be disastrous for farmers and the environment. 

“Unless management practices change, it’s only going to get worse,” said Aaron Gassmann, an Iowa State University entomologist and co-author of a March 17 Proceedings of the National Academy of Sciences study describing root worm resistance. “There needs to be a fundamental change in how the technology is used.” 


First planted in 1996, Bt corn quickly became hugely popular among U.S. farmers. Within a few years, populations of root worms and corn borers, another common corn pest, had plummeted across the midwest. Yields rose and farmers reduced their use of conventional insecticides that cause more ecological damage than the Bt toxin.

WAR OF WORLDS..

Form time to time we have a little fun with news events  in order to drive home a point more dramatically. While there are no War of the World Bugs invading croplands this satire reminds us that we are often playing with natures rules that are open to random mutations. In other words - WHO KNOWS?
