Today’s blog is brought to you by Margaret Thatcher, who addressed the UN General Assembly in 1989. Excerpts follow.
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 which are changing the environment of our planet in damaging and dangerous ways.
It is of course true that none of us would be here but for the greenhouse effect. It gives us the moist atmosphere which sustains life on earth. We need the greenhouse effect—but only in the right proportions.
Put in its bluntest form: the main threat to our environment is more and more people, and their activities: The land they cultivate ever more intensively; The forests they cut down and burn; The mountain sides they lay bare; The fossil fuels they burn; The rivers and the seas they pollute.
The result is that change in future is likely to be more fundamental and more widespread than anything we have known hitherto. Change to the sea around us, change to the atmosphere above, leading in turn to change in the world's climate, which could alter the way we live in the most fundamental way of all.
That prospect is a new factor in human affairs. 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. Whole areas of our planet could be subject to drought and starvation if the pattern of rains and monsoons were to change as a result of the destruction of forests and the accumulation of greenhouse gases.
We have to look forward not backward and we shall only succeed in dealing with the problems through a vast international, co-operative effort.
We should always remember that free markets are a means to an end. They would defeat their object if by their output they did more damage to the quality of life through pollution than the well-being they achieve by the production of goods and services. [our emphasis]
Mr President, the environmental challenge which confronts the whole world demands an equivalent response from the whole world. Every country will be affected and no one can opt out.
Reason is humanity's special gift. It allows us to understand the structure of the nucleus. It enables us to explore the heavens. It helps us to conquer disease. Now we must use our reason to find a way in which we can live with nature, and not dominate nature.
We need our reason to teach us today that we are not, that we must not try to be, the lords of all we survey.
We are not the lords, we are the Lord's creatures, the trustees of this planet, charged today with preserving life itself—preserving life with all its mystery and all its wonder.
May we all be equal to that task.
