ABSTRACT
The natural ecosphef'e u1Ulef' t1welJt .from humllu aet'tvities The greatest challenge that confronts society and governments today, and the generations to come, is the sustainable development and intelligent management of this (some would argue over-populated) planet. In essence, societies must be able to supply sufficient food, energy, raw materials and any required manufactured products to their citizens and other nations without compromising the world's resources for future generations, and without leaving a barren wasteland of environmental degradation. Putting such lofty ideals into practice is no easy task.
