Bioethics is the study of ethical questions and problems within the field of biology.

The Presidential Commission for the Study of Bioethical Issues (PCSBI) published a report in December 2010 regarding the ethical ramifications of synthetic biology. This report was requested by U.S. president Barack Obama in response to the announcement in May 2010 of the first self-replicating synthetic genome, belonging to the organism Mycoplasma mycoides JCVI-syn1.0.

iGEM teams are required to document their safety practices and the ethical implications of their projects[1].

Objections to synthetic biology

The term "synthetic biology" could almost be calculated to elicit a strongly negative response by anyone with a belief in the beauty of naturally evolved DNA.

According to the PCSBI, there were "...relatively few objections from religious or secular ethicists concerning the present status of the field"[2]. However, there are common concerns regarding the normal use (i.e. not abuses such as bioterrorism) that originate from both religious and secular philosophies. The phrase "playing god" is often used as a shorthand for decrying a particular experiment or procedure as being unnatural, and therefore unethical.

Secular objections to synthetic biology can be found in the "Deep Ecology" philosophy, which emphasizes the right to life of all living things without regard to their value to humanity. Intrinsic to this philosophy is opposition to humanity's current domination and control of Earth. Therefore, the efforts of synthetic biologists to finely control organisms (albeit simple single-celled organisms) represent the latest attack by humanity on Nature. It is doubtful any reconcilliation between scientists and deep ecologists could be made, given that a fundamental property of science is the testing and quantification of the natural world.


The tools of synthetic biology can be considered "dual-use" technologies, which can be used for both productive, useful applications, but also for weapons of mass destruction. Therefore, synthetic biology's potential to benefit humanity must be weighed against the potential development of bioweapons. The creation of such bioweapons may be simply the reconstruction of a previously eradicated disease such as smallpox[3], increasing the lethality of existing diseases[4], or create entirely new diseases. A key consideration when weighing these possibilities is the resources and knowledge required to create a bioweapon. Will our biological future mirror the computing world, where malicious programs are easily available for relatively inexperienced hackers, and the most sophisticated are used in cyberwarfare between antagonistic nations?

In the past, creating a bioweapon would require resources and training that was only available to few organizations, such as the Soviet Union and the United States during the Cold War. Naturally, this severely limited the possibility of a biological attack to events such as a world war. However, by extrapolating from current trends in DNA synthesis costs, computer aided design, and increases in the sophistication of DIY biology, it is possible a single individual could create a bioweapon. Returning the computer virus analogy, humanity could experience a future where the biological equivalent of black-hat hackers release viruses into the world. However, instead of stealing credit card numbers or emptying bank accounts, these "biohackers" could be introducing a lethal strain of the common cold, or an aerosolized ebola virus. Unfortunately, it is difficult to imagine how such a future could be prevented without draconian restrictions on the use of tools and techniques required for beneficial biological research.
