Under The Microscope

GREEN ISSUES FOR SCIENCE STUDENTS, by David Blaker; Longman Paul 1994; 54pp; $19.95

Reviewed by Donald Reid

Conservation topics can be desperately boring. The thought of saving another whale can generate a bout of yawning, or worse -- guilt -- yet this book sets a refreshing and stimulating model for conservation education, and shows particular attention to detail.

Somewhat unusually, it is divided into six case studies (marine matters, waste disposal, kereru decline, cetaceans and humans, timber usage and hydro-electric power generation) and is followed by an informative section on how to be pro-active with green issues. At the start of each of these case studies, students are asked to assess their present points of view and knowledge, then, most importantly, justify their statements.

This is one aspect of the book that most impresses, for rather than trite, hackneyed cliches, borne of some collective human guilt, of what we are doing to the planet, students must present facts and are challenged by questions such as "is it fair to criticise those who grow cocaine or cut down forests?".

Readers are encouraged to research topics for themselves, and the skills required are well explained. This is not new, but what is different is that basic information is provided, such as toxic timber preservatives and their relation to rain forest depletion, providing a launching pad for argument. A guide of where to go next and contact address are included.

Generally the data seems clear, concise and plausible, but like conservation itself, some are controversial. The research techniques on the Hectors dolphins population and the proportion of forests burnt by Pakeha are examples.

The second section addresses skills needed by students to argue effectively. The urgency and enthusiasm of the author is evident, and one wonders if urging students to be so pro-active isn't going to result in student anarchy, yet this topic needs it more than most. A focused approach is evident throughout the book, with clear definitions and icons that ensure students know exactly what is required for success.

The graphics are particularly varied, clean of line and delightfully clear. The choice of photographs and their presentation is quite outstanding. Even the final page, with its "Third Planet Operating Instructions", is thought-provoking, emotive and creative

As a classroom resource I will use it without the fear of yawning and with renewed enthusiasm.
