Living Carbon, located outside of San Francisco, is a biotechnology company that has produced genetically modified poplars. This genetically modified poplar can grow at an accelerated rate and in so doing consume more carbon dioxide from the air. To date this is all experimental and the company has only been successful in growing these plants in greenhouses. Over a five-month period indoors, these poplars grew 50% faster. Photosynthesis is the process in which enables plant life to thrive. The hope is that these genetically modified trees will use this process more efficiently in turn absorbing more carbon dioxide from the air. At present only a small field trial is under way to see how these trees grow outside the greenhouse. There is resistance from researchers who fear that these trees, since they are genetically modified, will cross pollinate with other trees. The positive side is that these trees can hopefully replace the problem we are facing with deforestation from the lumber industry.
