Global Coalition Sounds the Alarm on Synthetic Biology, Demands Oversight and Societal Debate.
Today, a coalition of thirty-five international organizations including scientists, environmentalists, trade unionists, biowarfare experts and social justice advocates called for inclusive public debate, regulation and oversight of the rapidly advancing field of synthetic biology - the construction of unique and novel artificial life forms to perform specific tasks. Synthetic biologists are meeting this weekend in Berkeley, California where they plan to announce a voluntary code of self-regulation for their work (1). The organizations signing the Open Letter are calling on synthetic biologists to abandon their proposals for self-governance and to engage in an inclusive process of global societal debate on the implications of their work (see attached Open Letter).
"The researchers meeting in Berkeley acknowledge the dangers of synthetic biology in the hands of 'evildoers,' but they naively overlook the possibility - or probability - that members of their own community won't be able to control or predict the behavior of synthetic biology or its societal consequences," said Jim Thomas of ETC Group. "Scientists creating new life forms cannot be allowed to act as judge and jury," explains Dr. Sue Mayer, Director of GeneWatch UK. "The possible social, environmental and bio-weapons implications are all too serious to be left to well-meaning but self-interested scientists. Proper public debate, regulation and policing is needed."
In the last few years, synthetic biologists, by re-writing the genetic code of DNA, have demonstrated the ability to build new viruses and are now developing artificial life forms. In October last year, synthetic biologists at the US Center for Disease Control re- created the 1918 Spanish flu virus that killed between 50-100 million people (3) and last month scientists at the University of Wisconsin- Madison created a new version of E. coli bacteria (4). Meanwhile, genomics mogul Craig Venter, whose former company, Celera, led the commercial race to sequence the human genome, now heads a new company, Synthetic Genomics (5), that aims to commercialize artificial microbes for use in energy, agriculture and climate change remediation. It is one of around 40 synthetic biology companies undertaking gene synthesis and/or building artificial DNA. "Biotech has already ignited worldwide protests, but synthetic biology is like genetic engineering on steroids," says Dr. Doreen Stabinsky of Greenpeace International. "Tinkering with living organisms that could be released in the environment poses a grave biosafety threat to people and the planet," adds Stabinsky.
In October 2004, an editorial in the journal Nature warned, "If biologists are indeed on the threshold of synthesizing new life forms, the scope for abuse or inadvertent disaster could be huge."
The editorial suggested that there may be a need for an "Asilomar- type" conference on synthetic biology - a reference to an historic meeting in 1975 where scientists met to discuss biosafety risks associated with genetic engineering and opted for self-governance which ultimately pre-empted and avoided government regulation. Following the Asilomar model the "Synthetic Biology Community" intends to use their second conference (Synthetic Biology 2.0, 20-22 May 2006) to adopt a code of self-governance for handling the biosafety risks. According to the Open Letter, the effect of the Asilomar declaration was to delay the development of appropriate government regulation and to forestall discussion on how to address the wider socio-economic impacts. Asilomar proved to be the wrong approach then, and Synthetic Biology 2.0 is the wrong approach now. "We scientists must come to terms with the fact that science can no longer claim to be living in an abstract realm disconnected from the rest of society," said Alexis Vlandas of International Engineers and Scientists for Global Responsibility (INES). The signatories to the Open Letter urge the synthetic biologists meeting in Berkeley to withdraw their declaration of self-governance and join in seeking a wider, inclusive dialogue.
