I am very happy and very honoured to have been invited to give the inaugural lecture in the series under the Sir Hersch Lauterpacht Chair of Public International Law at the Hebrew University of Jerusalem. It is a great honour to be connected with the name of Hersch Lauterpacht who was one of the truly great minds in the field of international law in our epoch, great as a scholar, great as an idealist, an innovator and a prophet; and it is a source of happiness to me to bear witness to the fact that he was also a great human being whose wisdom was illuminated with kindness and warmth. His friends and pupils remember him with love and gratitude.
For the purpose of this paper I invite you to accept with me the proposition that we live in an ecological crisis. The extent of the dangers confronting us is in dispute. The degree of urgency is debated. There are still serious gaps in our knowledge. The task of the scientists is enormous. Still, no one can ignore the existence of this crisis.
“The two worlds of man, the biosphere of his inheritance, the technosphere of his creation—are out of balance, indeed potentially in deep conflict. And man is in the middle. This is the hinge of history at which we stand, the door of the future opening on to a crisis more sudden, more global, more inescapable and more bewildering than any ever encountered by the human species and one which will take decisive shape within the life span of children who are already born.”
