There are three modes of navigation – perspectives, linear and glossary.

• The perspectives mode presents a number of contrasting viewpoints on specific topic areas.

• The linear mode enables you to work through the contents of the whole module in a systematic way, from beginning to end.

• The glossary mode enables you to look up key words, and track into the main segments of the module where those words are used.

First, go into the perspectives mode. In module three this presents the views of an industrialist, an environmentalist, a senior citizen and a civil servant on four different topic areas – energy, air, waste, and water.
