US-backed researcher scours seas for matter to create life

By Stephen Leahy

Brooklin, Canada, Aug. 19 (IPS)— Somewhere in the South Pacific Ocean, a private research vessel owned by controversial genetic scientist J. Craig Venter is collecting millions of bacteria from the sea, hoping to find the biological building blocks he can use to create a synthetic life-form that will one day become a new source of energy.

As fantastic as it sounds, US scientists, including Venter, have already created such life forms from bits of DNA, the building blocks of the cells that make up all living things.

For instance, in 2002, geneticists at the State University of New York manufactured a polio virus. While that effort took years, Venter assembled a bacteriophage — a virus that infects bacteria — in less than two weeks late last year.

The process is called synthetic biology or nano-biotechnology, and uses pieces of DNA and individual molecules to build what are in essence living machines.

Venter and his peers are scouring the planet for bacteria that are much more efficient than known varieties at converting sunlight and biological matter into energy, the basis for the alternative energy source “biomass,” which turns agricultural and other biological waste into fuel.

The DNA of those “super” bacteria would then provide the blueprint for the living machines.

Creating the artificial bacteriophage involved making copies of segments of DNA from a real bacteriophage and putting them together inside a bacterial cell. The artificial bacteriophage looks and behaves just like the natural one: it has the ability to infect and kill bacterial cells and is indistinguishable from its “real” counterpart.

A bacteriophage is a very simple life form, with just 5,000 base pairs in its genome or genetic map. (By contrast, the human genome has three billion base pairs.) Bacteria have roughly four million base pairs, and creating an artificial one will be much, much more complicated.

But there are those who believe it can be done. And, the US Department of Energy (DOE) thinks Venter is the scientist for the job.

Last year the DOE gave Venter’s organization, the Institute for Biological Energy Alternatives (IBEA), nine million dollars to create artificial organisms that reduce the amount of carbon dioxide in the atmosphere and to produce biological energy sources.

“With this advance,” Secretary of Energy Spencer Abraham said in a statement, “it is easier to imagine, in the not-too-distant future, a colony of specially designed microbes living within the emission-control system of a coal-fired plant, consuming its pollution and its carbon dioxide, or employing microbes to radically reduce water pollution or to reduce the toxic effects of radioactive waste.”

But other observers see a more frightening future.

“The creation of new life-forms has enormous implications for all humankind,” says Silvia Ribeiro of the environmental non-governmental organization ETC Group.

“This is potentially much riskier than GM (genetically modified) crops. Releasing completely new forms of life into the world might open a Pandora’s box,” she told IPS from her Mexico City office. “There should be an open, public debate about this.”

IBEA did not reply to IPS’ requests for an interview.

Brewster Kneen, a Canadian writer and biotechnology critic, sees Venter’s quest as more of the US government’s continuing promotion of biotechnology as the solution to all problems. “Rather than making real efforts to deal with the sources of pollutants, they try to distract people with this ‘magic bullet’ thinking,” he said in an interview.

Serious problems such as climate change need attention now, added Kneen, publisher of The Ram’s Horn, a journal of food systems analysis, but Washington has done little to reduce US emissions of the greenhouse gases believed to cause global warming, nor has it signed the Kyoto Accord — an international treaty designed to cut emissions.

David Caron, a marine biologist at the University of Southern California (USC), says Venter’s project has the potential to solve some environmental problems but is a very long-term proposition. “We can’t even guess what they’ll find,” he told IPS.

An expert on marine microorganisms, Caron says bacterial diversity is nearly limitless and therefore has great potential to contribute to the development of useful products. For those reasons and to better understand marine ecology, many other scientists are looking at ocean bacteria, but on a smaller scale than Venter, he added.

The biologist supports this type of research and is working with other scientists at USC to one day deploy millions of microscopic robots or “nano-bots” in the ocean to monitor outbreaks of toxic algae. The project will take at least a decade to achieve, if it ever succeeds, but Caron points out that in the 1960s the idea of the internet seemed far-fetched to many people.

Yet the world is anteing up for nano-technology. Investment in it will total $8.6 billion in 2004, and the US government will contribute $3.7 billion into “nano” research over the next four years, New York-based Lux Research Inc announced Aug. 17.

Tiny robots are less of a concern than putting artificial life forms, which might reproduce or mutate, into the environment, says Sheldon Krimsky, professor of environmental policy at Tufts University in Massachusetts.

Creating new life-forms from the bottom up will not make them any safer than current biotechnologies, says Krimsky, who has written several books on the subject. “The chemical industry creates its products that way and has had a phenomenal history of mistakes.”

One major reason for those errors, which include PCBs — toxic chemicals used as coolants and in electrical products and that are released into the environment as by-products of incineration — results from a simplistic view of biology when, in fact, all living things co-exist in a complex ecosystem of inter-relationships, Krimsky said in an interview.

Synthetic biology, he argues, fits into the same model of linear thinking that believes creating life is just a matter of putting the right biological building blocks together.

Researchers are creating life forms without any public or governmental oversight, adds Krimsky, and that shows no sign of changing, he said. “Until products are ready to leave the labs, there will be no public attention on this issue.”

ETC Group’s Ribeiro and members of other civil society organizations that met at the first Americas Social Forum in Quito, Ecuador in July say they are now trying to increase public awareness. They have also agreed to create a network to track Venter’s work and to discuss its implications.

They are also concerned about possible patents of life forms, although Venter has signed memorandums of understanding (MOUs) or other agreements with countries where he has taken bacteria samples.

But such deals have not been subject to debate nor have the terms been made available publicly despite Venter’s assurances they would be, says Ribeiro.

According to Chilean activist Camila Montecinos, “there is nothing in the MOU with Chile or the Galapagos to prevent monopoly patent claims on any commercially useful results derived from our collected diversity.”

“We are profoundly troubled by the potential of Venter or others to privatize microbes found in our region,” she added in a statement issued by Spain-based organization GRAIN, an NGO that promotes the sustainable management and use of agricultural biodiversity based on people’s control of genetic resources and local knowledge.

Ribeiro said many delegates at the Quito forum were calling Venter’s project the “mother of all bio-piracies” and were extremely worried about the dangers inherent in creating entirely new forms of life. “Doing this is both dangerous and arrogant,” she says. “Is this the kind of science we need in the world today?”

GM clash in French corn field

By Alex Duval Smith

Paris, France, Aug. 17— A new front has opened up in the controversy over genetically modified organisms (GMOs) in food with the surprise emergence in France of a group of radical rural campaigners claiming to be in favor of open-field experiments.

In a corn field near Marsat in the Puy-de-Dôme at the weekend, gendarmes intervened after the anti-globalization campaigner José Bové and 500 of his supporters came to blows with a new group describing itself as “volunteer farmers and researchers in favor of GMO tests.”

The clash came amid growing signs that the French authorities are wavering in their opposition to open-field tests of GM crops, the seeds of which are developed in laboratories to be resistant to certain pests or to herbicides. In recent weeks even the conservative French wine-growing industry has announced it wishes to keep an open mind over the possible benefits of GMOs.

The weekend clash, which resulted in two arrests, was the first physical confrontation between the two camps. France -- where anti-GMO campaigners trample experimental crops most weekends -- has become Europe’s main battleground over the issue, but police rarely intervene and most confrontations have been confined to courtrooms. Bové has called on his supporters -- known as “the volunteer reapers” -- to step up their campaign of civil disobedience before a European Commission decision on the issue due this autumn.

The commission, which in May for the first time authorized the planting of a genetically modified maize seed manufactured by the Swiss company Syngenta, is divided and must decide by November whether to authorize the US chemical giant Monsanto to sell its transgenic NK603 maize in the EU.

Bové’s “volunteer reapers” said yesterday that the emergence of a group campaigning in favor of open-field tests was an attempt by the GMO industry to give a “grassroots flavor” to its efforts to win over public opinion.

The Green MP Moisette Crosnier said: “Eighty percent of Europeans are against GMOs in their food and 75 percent of French people are opposed to open-field experiments. We have to keep up the pressure on the government and remind it of the will of the people.” So far only 21 open-field GMO tests have been authorized on 48 plots totaling 18 acres.

However, the “volunteer reapers” have strong grassroots support and have convinced 3,000 French mayors to ban GMO tests in their area. One mayor, in Bax, Haute-Garonne, is facing court action by the prefect of his département who wants to overrule him. Last year, Bové served six weeks in prison for destroying GM crops and he is due to be interviewed by police next week over an incident in Haute-Garonne at the end of July.

The “volunteer farmers and researchers in favor of GMOs” are led by Pierre Pagesse, a farmer and the managing director of the French biotechnology firm Biogemma. He says he launched his group because the “continuing destruction of crops is playing into the hands of France’s competitors.”

He said: “At this rate European farming will fall behind. To have sustainable agriculture you first of all need to sustain the farmers.”

Pagesse is president of Limagrain, a leading European seed company of which Biogemma is the research arm.

Despite popular opposition to GMOs, the farming industry and French scientists are increasingly arguing that the phenomenon is unstoppable. The agriculture ministry has begun a process of public consultation by internet and a report by the French food security agency, AFSSA, last month claimed that GM maize and cotton, as well as beetroot and rice, showed health benefits.
