Today, every inhabitant of this planet must contemplate the day when this planet may no longer be habitable. Every man, woman and child lives under a nuclear sword of Damocles, hanging by the slenderest of threads, capable of being cut at any moment by accident, or miscalculation, or by madness. The weapons of war must be abolished before they abolish us.
John F. Kennedy
In an address before the General Assembly of the United Nations on September 25, 1961.
We will not prematurely or unnecessarily risk the costs of a worldwide nuclear war in which even the fruits of victory would be ashes in our mouth — but neither shall we shrink from that risk any time it must be faced.
John F. Kennedy
Radio address about the Cuban missile crisis (22 October 1962)
Although September 11 was horrible, it didn't threaten the survival of the human race, like nuclear weapons do.
Colonies in space may be only hope, says Hawking
The dinosaurs disappeared because they could not adapt to their changing environment. We shall disappear if we cannot adapt to an environment that now contains spaceships, computers — and thermonuclear weapons.
Forward to The Collected Stories
As scientists, we understand the dangers of nuclear weapons and their devastating effects, and we are learning how human activities and technologies are affecting climate systems in ways that may forever change life on Earth. As citizens of the world, we have a duty to alert the public to the unnecessary risks that we live with every day, and to the perils we foresee if governments and societies do not take action now to render nuclear weapons obsolete and to prevent further climate change...There’s a realization that we are changing our climate for the worse. That would have catastrophic effects. Although the threat is not as dire as that of nuclear weapons right now, in the long term we are looking at a serious threat.
