Lesson 5: Module Case Study
Topic 1: Energy Grass
You are in charge of Risk Communication (RC) for the National Plant Protection Organization in your country of Everywhere.
A powerful industry in Everywhere, AGE (Affordable Green Energy) Inc., would like to import a new hybrid plant species that can be used to produce ethanol (biofuel). Together with international partners, they have developed a new hybrid species that appears to be a good candidate. It is a cross between sweet grass and a weed species.
