Aubrecht, K. B. et al. “Graphical tools for Conceptualizing Systems Thinking in Chemistry Education” J. Chem. Ed. 2019, 96, 2888−2900.  You are giving a talk to an audience of University students with a diverse understanding of green and sustainable concepts. How would you use systems theory and/or diagrams to teach one of the following (your choice, pick one) to your audience? Choice A: The role circular and linear economies play in creating a greener and more sustainable society. Choice B: How E- and F-factors can be used to make greener and more sustainable production choices. 

Consider this diagram about converting biomass to useful products: biomass to useful products.pdf (click link. Honorlock may not allow you to download.). In the diagram: All numbers are kilograms. Each scenario starts with 100 kg biomass. AC means activated carbon. Pyrolysis, Activation, Water-gas shift, and F-T are transformative processes/reactions. Biochar and activated carbon (AC) can be mixed with soil to permanently sequester carbon. Fuels release CO2 into the atmosphere when used. Which scenario has the greatest potential to permanently remove (“sequester”) carbon from the atmosphere?

Consider your reading and the class discussion of “The water footprint of humanity” by Arjen Y. Hoekstra and Mesfin M. Mekonnen. Explain to a policy maker why water trade should or should not be regulated to reduce and/or prevent water strain.  Correct responses will address the use of water resources to support society’s endeavors and how society can act to reduce water strain.
