Following are brief excerpts from an "Urgent Warning to Humanity" which was issued by sixteen hundred Nobel prize winning and other scientists from around the world in 1992:
"Human beings and the natural world are on a collision course. Human activities indict harsh and often irreversible damage on the environment and on critical resources. If not checked, many of our current practices put at serious risk the future that we wish for human society and the plant and animal kingdoms, and may so alter the living world that it will be unable to sustain lile in the manner that we know. Fundamental changes are urgent if we are to avoid the collision our present course will bring about...."
"No more than one or a few decades remain before the chance to avert the threats we now confront will be lost and the prospects for humanity immeasurably diminished...."
"We the undersigned senior members of the worlds scientific community, hereby warn all humanity of what lies ahead. A great change in our stewardship ol the earth and the lile on it is required, if vast miseries are to be avoided and our global home on this planet is not to be irretrievably mutilated."
