In April of 1990, a three-day conference was convened at which 76 men and women from 18 countries representing a spectrum of government, business, labor, academia, the media, and the professions gathered to discuss how the United State should reorient its policies and relations toward other countries and international institutions to preserve the global environment. This document is a statement produced by the conference participants after the close of their discussions. The statement contends that three indivisibly linked global environmental trends together constitute an increasingly grave challenge to the habitability of the earth. These trends, which are discussed, are human population growth; tropical deforestations and the rapid loss of biological diversity; and global atmospheric change, including stratospheric ozone loss and greenhouse warming. The statement also outlines the goals and means of international cooperation and challenges. The United States must play a key leadership role in global environmental issues both by example and through international participation. (DB)
