GMOs? Savour for feeding a hot world?

Stark realities confronting us all....

"Eduardo Blumwald’s genetically modified plants don’t look much like “Frankenfood.” Filling four modest greenhouses in a concrete lot behind Blumwald’s laboratory at the University of California, Davis, the tiny seedlings, spiky grasses, alfalfa, and peanut and rice plants in plastic terracotta-colored pots look exactly like the ordinary varieties from which he and his fellow researchers created them. Blumwald’s lab lies just ten miles from Monsanto’s 90,000-square-foot vegetable seed building, a glassy edifice larger than the hangar for a 747. The Monsanto facility is one of the largest centers in the world for plant breeding and genetic engineering. But in the fourteen years that Blumwald, a professor of cell biology, has worked here studying the DNA of crop plants, he has hardly ever spoken to anyone from Monsanto."

Blue-eyed and round-faced, with a lilting Argentinian accent, Blumwald grows exasperated when he talks about the so-called “Big Ag” companies, which he says have been arrogant in dealing with the public, contributing to a distrust of biotech research. But he also doesn’t appreciate the activists who’ve been challenging not only the Monsantos of the world but the entire field of genetic engineering.

“You want to penalize the multinationals; I have no problem with that,” he tells me in his office at the university’s plant biology building. “But because of your political stance against multinationals, you are going to condemn maybe the only viable solution we have for our future? It’s wrong—absolutely wrong.”

Blumwald means the hot future that we expect by 2050—when a world population of 9.5 billion people will scramble to put food on the table, while at least thirty-seven separate countries face extreme water crises. Blumwald thinks that part of the answer is to genetically engineer crops that can better withstand drought, and so he and his researchers are scouring the world for varieties of fruits, vegetables and some basic staples—rice, millet, wheat, maize—that grow well without much water. Then, using a device called a “gene gun,” which inserts DNA on microscopic gold particles, or a soil bacterium capable of changing plant genes, they alter or silence parts of the plant’s genome, adjusting how and when the plant makes the hormones that let it know when to grow and when to wither. The researchers say the methods are more precise and much faster than developing new plant varieties by conventional breeding, which can take decades.

When I tour the rows of rice and peanuts with one of Blumwald’s assistants, a postdoctoral researcher from Madrid, the air in the greenhouse is soupy. About two dozen researchers work in Blumwald’s lab, many of them from hot parts of the world with swelling populations, including Brazil, China and the United Arab Emirates. In the greenhouse, the researchers force the rice to cope with heat and deprive it of water just as it’s about to set seed. So far, the genetically altered rice is outperforming the natural kind—given less moisture, the non-engineered rice browns and wilts, but the new plant survives. Blumwald’s goal is to create crops that won’t keel over as quickly when things get hot, dry and stressful—plants that will improve the odds that a farmer can produce food even in a drought."

Big Brother alive and well in the USA in 2007

The so-called "war on terror" has shown itself up in a multitude of manifestations. The most dangerous thing has been governments using the "excuse" of the war to restrict certain civil liberties, allowing government agencies to pursue a variety of things that they would otherwise would not - and should not - be allowed to do and gathering, and retaining, a variety of information on its citizens.

The Washington Post reports on the latest incursions into civil liberties of all Americans:

"The U.S. government is collecting electronic records on the travel habits of millions of Americans who fly, drive or take cruises abroad, retaining data on the persons with whom they travel or plan to stay, the personal items they carry during their journeys, and even the books that travelers have carried, according to documents obtained by a group of civil liberties advocates and statements by government officials.

The personal travel records are meant to be stored for as lo…

Whatever democracy the Palestinians had is dying

Almost a desperate cry from a well-known, respected and sober moderate Palestinian.

Mustafa Barghouthi is secretary-general of the Palestinian National Initiative and a member of the Palestinian Legislative Council. He was a candidate for the Palestinian presidency in 2005.

He writes in a piece "The Slow Death of Palestinian Democracy" on FP:

"Palestinian municipal elections were supposed to be held last week. Instead, they were canceled. A statement released by the Palestinian Authority claimed the cancellation was "in order to pave the way for a successful end to the siege on Gaza and for continued efforts at unity" between Hamas, which governs the Gaza Strip, and the government in the West Bank.

The cancellation of this election was an unjustified, unlawful, and unacceptable act. It damages democratic rights and makes a mockery of the interests of the Palestinian people.

But this is far more than an internal Palestinian issue. The only lasting peace between Isr…
