to convey this concern in a lucid manner. We failed totally to get the
concept of 'overshoot' accepted as a legitimate concern for public debate"
(p. XX).
This then is the focus of the new book: ecological overshoot, and systems
collapse, but also the possibilities of transition towards a sustainable
development path on planet Earth. "Our main goal is to restate our 1972
argument in a way that is more understandable and better supported by the
data and examples that have emerged during the past decades. In addition,
we wish to give the many teachers who use our earlier text updated
materials for use with their students" (p. XVIII).
The global challenge, the authors believe, can be simply stated: To reach
sustainability, we must increase the consumption levels of the world's poor,
whilst at the same time reducing humanity's total ecological footprint. To
do so, not only are technological advances needed, but also personal
change, and longer planning horizons. There must be greater respect, caring
and sharing across political boundaries. But so far, the authors argue, no
political party really has garnered broad support for such a program,
certainly not among the rich and powerful. Meanwhile, the total human
ecological footprint gets larger day by day (on this, see pp. XV).
An important methodological innovation of this book is a calibration of the
computer model World 3 from 1991. An indicator of the well-being of the
average world citizen is integrated, called the human welfare index (HWI),
and an indicator of humanity's total environmental impact on the planet is
added, the human ecological footprint (HEF). While the first indicator
approximates the UNDP Human Development Index, the second is an
adaptation of Mathis Wackernagel's ecological footprint concept. The
resulting new model, called World 3-03, is available on a CD-ROM
