to the question of whether we as humans can adapt our lifestyles in the pursuit of an environmentally sound world. Inadequate information is a limiting factor, and unforeseen events make uncertainty inevitable. Even so, choices made today can narrow or expand future options.

Special emphasis is given to the interactions of environmentalism and science in generating public and international environmental policies.
