The Problem

---

The pace of modern technology is astounding: the dreams of yesterday have already become reality, and we are closer than ever to flying cars, human cloning, and settlement on the moon. But technology marches on at the expense of our planet. The past hundred years have marked the depletion of the ozone layer, rainforest destruction, extinction of different species of animals and plants, and the manufacturing of massive amounts of garbage.

Partial efforts to combat these unwanted effects are already in place, such as recycling, green architecture, and efforts against global warming. But these macro-level solutions are not enough, and do not solve all of the by-products of technological advances. Pesticides, for example, affect the base of the food chain and seep into the groundwater. For problems like these, a micro-solution is necessary: micro-organisms.

Why Micro-Organisms?

Micro-organisms service us in many aspects of everyday life. Yeast makes beer and bread, lactic bacteria makes cheese, algae and zooplankton help treat sewage.


What if microbes could be programmed to fulfill any needed function?

Synthetic biology is the engineering of biology: the systematic addition of functions to biological systems. Potentially, microbes could be modified to fulfill any needed purpose, from the microscopic to the large-scale, like genetically engineering bacteria to help fight climate change[1].

The traditional uses of micro-organisms have proven themselves to be safe over time, but what about the new? Because of the complexity of biological and ecological systems, the environmental effects of releasing GMOs is difficult to predict. Another problem is that synthetic biology is becoming increasingly accessible, making it possible for individuals outside of an academic or industrial context to create and release potentially dangerous GMOs. Once released, GMOs cannot be contained or controlled, making any damage potentially irreversible. Lastly, GMOs may pose risks that we do not know enough to imagine. Because of these groups like Greenpeace are vehemently opposed to the release of GMOs, and even among supporters of synthetic biology, there is concern about possible risks.
