3 Hot dry rock (HDR) fields
Energy from sources other than fossil and nuclear fuels is to a large extent free of the concerns about environmental effects and renewability that characterise those two sources. Each alternative source supplies energy continually, whether or not we use it. This unit considers one of these alternative sources, geothermal energy derived from the interior heat of the Earth, and the potential for this alternative to supplant fossil and nuclear fuel use to power social needs fast enough to avoid t

6 Summary
The transformation of radioactive uranium and, in some instances, thorium isotopes provides vastly more energy per unit mass of fuel than any other energy source, except nuclear fusion, and therein lies its greatest attraction. The unit considers the advantages and limitations of generating this power and the environmental and security issues that the process raises.

Unit questions
The extreme challenges of life in the polar regions require the animals who make their habitat there to make many adaptations. This unit explores the polar climate and how animals like reindeer, polar bears, penguins, sea life and even humans manage to survive there. It looks at the adaptations to physiological proceses, the environmental effects on diet, activity and fecundity, and contrasts the strategies of aquatic and land-based animals in surviving in this extreme habitat. This unit builds

"Chicago" by Carl Sandberg (poetry reading)
This poem was first published in 1916, a little earlier than Prohibition, Al Capone and the domination of the underworld: Chicago was relatively salubrious at that time. Here's Vincent Price reading it: http://www.vincentprice.org/audio/17%20Chicago.mp3 HOG Butcher for the World, Tool Maker, Stacker of Wheat, Player with Railroads and the Nation's Freight Handler; Stormy, husky, brawling, City of the Big Shoulders: They tell me you are wicked and I believe them, for I have seen your painte

Last Stand of the Great Bear
This hour long video tells the story of a 250-mile adventure through unspoiled territory along the coast of British Columbia called the Great Bear Rain Forest. It is here that bear-hunting wolves take to the sea, grizzlies clash in titanic battles and wild salmon are the pulsing lifeblood of an entire ecosystem. As this precious habitat faces an uncertain future, threatened by chainsaws and fish farms, a team of dedicated scientists is racing to prove that it must be protected. Forming a wildern

2.3 Using conversation to construct environmental responsibility
This unit focuses on the substance of environmental responsibility – what matters. The question ‘What should constitute our prime focus of attention?’ can prompt different responses. We consider two points of contrast in differing focuses on what matters: 1 a distinction between nature and the environment 2 a distinction between nature/environment and related human interactions

5.8 Conclusion
Life is full of risk. In this unit ‘risk’ describes the probability and consequences of harm or, at worst, disaster. Risk management involves many stakeholders and integrated management systems help to ensure that safety, quality, environmental and business risks are all managed correctly. This unit also looks at emergency preparedness, that is, the management of emergencies and disasters.

3.4 Discussion
Global warming: are we responsible? Is our environmental impact damaging the planet? This unit examines the use of ozone depleting technology, the impact of fossil fuel use and explores how the development of technology can influence the direction of a society. From the Industrial Revolution to the present day find out how we have changed the planet.
