4.2 Reactor safety: the Chernobyl incident
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.

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.

3.6 Indicators
There is increasing recognition that the reductionist mindset that is currently dominating society, rooted in unlimited economic growth unperceptive to its social and environmental impact, cannot resolve the converging environmental, social and economic crises we now face. The primary aim of this unit is to encourage the shift away from reductionist and human centred thinking towards a holistic and ecological worldview.
