'The contributors to this volume undertake to establish the foundations and definitions of "intergenerational justice" and to explore its capacity to guide us in policy and public opinion judgments we must make to face unprecedented issues. . . We are changing the biosphere and using resources to an extent never contemplated in the history of ethics. Deterioration of our oceans, loss of topsoil, insecurity about potable water supplies, the ozone hole, global warming, and the question about how to handle high-level nuclear waste which remains lethal perhaps 400,000 years from now, are some examples whose consequences reach far beyond inherited principles and policies of responsibility to others. This Handbook works to open a path for debate, extension of our tradition and invention of new thinking on these issues.'
