Man’s activities, by the nineteen-nineties, had begun to threaten the conditions of human life on a terrestrial scale.

As the Cold War (the East-West conflict) eased, environmental observations and analyses led to the attention of leading politicians to global environmental risks. In 1972, the first global programme for the protection of the human environment was drawn up at the UN Conference in Stockholm.

At this global meeting, the participants adopted a joint declaration on the principles and responsibilities of environmental protection, in which the signatory governments committed themselves to making the earth’s environment a better and more liveable place for present and future generations of human beings.
