1-In developing countries, approximately 2.5 billion people rely on biomass to meet their energy needs.
In your opinion, is it ethical to use cropland for biofuel production in a world where some of the population still does not have adequate food? In 2-3 paragraphs, argue your view on this question.

3- During class, we listened to the NPR news report called Drought imperils hydropower on Colorado River’s reservoirs. This podcast (available on Moodle) focused on falling water levels at Lake Powell’s Glen Canyon Dam. Reflect back on what you heard OR Listen to the podcast again.
With the Cohen Framework in mind:
1) Describe how the hydropower AND low water levels in the Colorado River might be considered an ECONOMIC issue.
2) Describe how hydropower AND low water levels in the Colorado River might be considered an issue of VALUES.
See Cohen Framework worksheet on the Moodle class page for more information on how to think about environmental issues in terms of the Cohen Framework.
