James Hall – January 22, 2014
With Ben Shalom Bernanke set to depart on the last day of January 2014, the critique and speculation of his tenure as Chairman of the Federal Reserve begins. The mainstream financial press is giving mostly favorable accounts. Heretofore, such praiseworthy acclamations strike a shape contrast with the actual record of the state of the economy. However, the admirers of the Fed and his specific enactments live in a time warp that only masters of the universe encounter. For the remaining population, an intense struggle for survival is the actual experience, remembered from the Bernanke years.
Investopedia expresses a complimentary score of The Legacy Of Ben Bernanke, and cites distinguished highlights and concludes that “Under Bernanke’s stewardship, the Fed became the most transparent it has ever been in its history.”
Australian chemistry teacher James Kennedy has created a tongue-in-cheek set of images that take a fresh perspective on the public discussion about fresh and organic foods vs. the genetically modified products and chemical pesticides being championed by companies like Monsanto. His posters take all-natural products and break them down by their chemical composition, or their “ingredients.”
When we read the ingredient labels on the processed foods that we eat (or choose not to eat), there’s usually a long and worrisome list of chemical ingredients that we can’t identify. However, Kennedy’s series of images points out that our fear of some of these chemicals might be misplaced.
“I want to erode the fear that many people have of ‘chemicals’, and demonstrate that nature evolves compounds, mechanisms and structures far more complicated and unpredictable than anything we can produce in the lab,” writes Kennedy, who personally avoids buying any sort of food with monosodium glutamate (MSG) or high-fructose corn syrup.
“This poster series breaks down all the major ingredients in popular natural foods—using E-numbers and IUPAC [International Union of Pure and Applied Chemistry] names instead of common names where they exist. Anthocynanins, for example, which are said to give blueberries their ‘superfood’ status, are also known as E163,” he explained.

A man, a plan—and little else
NOT since the civil war of the 1980s have so many helicopters been clattering over remote parts of Nicaragua. But now the guys squinting down through the tree canopy are in suits: lawyers and business consultants from the United States, Australian engineers, British environmental auditors, even Chinese executives. Their per diems are being paid by Wang Jing, a Chinese businessman whose $40 billion quest is to build a canal from Nicaragua’s Atlantic coast to its Pacific one. (…)

Nicaragua canal boosts China power
Since it first opened in 1914, the Panama Canal has provided the primary shipping conduit linking the Pacific and Atlantic Oceans through the Americas. And in that time, it has also represented US dominance in the region. Even after the canal passed entirely into Panama’s control in 1999, the United States has maintained a strong military presence in the region, establishing its continuity as the region’s key economic and political player.
All that is about to change. (…)

A Nicarágua vai ser serrada a meio para juntar o Pacífico ao Atlântico
(…)Maior ameaça ambiental no país.
Mas acresce outra importante polémica o impacto ambiental de tão monumental obra. A consultora britânica Environmental Resources Management (ERM) foi contratada pela construtora para averiguar as consequências de escavar um canal profundo através do Lago da Nicarágua, o maior lago de água doce da América Latina, e de talhar terras ancestrais indígenas até chegar ao mar do Caribe. E tentar compensar os danos. (…)
