Peter Rowe is Co-founder of Deep Branch Biotechnology. Self-described as "helping to turn the polluters of today into the producers of tomorrow," Peter discusses the idea, method, and science behind Deep Branch. According to the World Business Council for Sustainable Development (WBCSD www.WBCSD.org), "Concrete is the most widely used material on earth apart from water, with nearly 3 tons used annually for each man, woman, and child." This is significant because the amount of CO2 emitted from its production is almost on a 1-to-1 ratio. Per 1 pound of concrete produced, there are about 0.9 pounds of CO2 emitted. Peter was trained as molecular microbiologist with specific interests in synthetic biology and genome editing technologies. We not only talk about his efforts to help solve some of the most pressing issues with CO2 emissions, but Peter also indulges us in a free-ranging conversation regarding his experience with CRISPR and the ethical issues posed about the use of this often controversial science.
