In November 8, 1989 she
told the UN: "While the conventional, political dangers - the threat of global annihilation, the fact of regional war - appear to be receding, we have all recently become aware of another insidious danger. It is the prospect of irretrievable damage to the atmosphere, to the oceans, to earth itself.
"What we are now doing to the world, by degrading the land surfaces, by polluting the waters and by adding greenhouse gases to the air at an unprecedented rate - all this is new in the experience of the earth. It is mankind and his activities that are changing the environment of our planet in damaging and dangerous ways."
She continued: "The result is that change in future is likely to be more fundamental and more widespread than anything we have known hitherto. It is comparable in its implications to the discovery of how to split the atom. Indeed, its results could be even more far-reaching.
"It is no good squabbling over who is responsible or who should pay. We shall only succeed in dealing with the problems through a vast international, co-operative effort.
