War contributes greatly to global warming, which shouldn’t surprise us. All those bombs going off, all those rockets, all those planes and helicopters. All that fuel of various kinds being used. It pollutes the air and water of this very fragile and interconnected planet.

What is absurd and monstrous about war is that men who have no personal quarrel should be trained to murder one another in cold blood.

Politics is the womb in which war develops.

The Washington leadership has put aside non-proliferation programmes and devoted its energies and resources to driving the country to war by extraordinary deceit, then trying to manage the catastrophe it created in Iraq.

We have always said that in our war with the Arabs we had a secret weapon – no alternative.

I venture to say no war can be long carried on against the will of the people.

In my view of the present aspect of affairs, there is no need of bloodshed and war. There is no necessity for it. I am not in favor of such a course, and I may say in advance, there will be no blood shed unless it be forced upon the government. The government will not use force unless force is used against it.

War had always seemed to me to be a purely human behavior. Accounts of warlike behavior date back to the very first written records of human history; it seemed to be an almost universal characteristic of human groups.

The argument that resistance to the war should remain strictly nonviolent seems to me overwhelming.

The first panacea for a mismanaged nation is inflation of the currency; the second is war. Both bring a temporary prosperity; both bring a permanent ruin. But both are the refuge of political and economic opportunists.

You can’t make war in the Middle East without Egypt and you can’t make peace without Syria.

War is never a solution; it is an aggravation.

Patriots always talk of dying for their country and never of killing for their country.

We’ve got to keep our eye on what’s happening with Russia and North Korea. We cannot lose sight of domestic policy, either. Healthcare. Immigration. Climate change.

I hate war as only a soldier who has lived it can, only as one who has seen its brutality, its futility, its stupidity.

If you destroyed half the pharmaceutical production in the United States, we’d think it’s a pretty serious problem. In fact, we’d probably go to war.

If atomic bombs are to be added as new weapons to the arsenals of a warring world, or to the arsenals of nations preparing for war, then the time will come when mankind will curse the names of Los Alamos and of Hiroshima.

Avoiding climate breakdown will require cathedral thinking. We must lay the foundation while we may not know exactly how to build the ceiling.

We are at a time in history where everyone with any insight of the climate crisis that threatens our civilisation – and the entire biosphere – must speak out in clear language, no matter how uncomfortable and unprofitable that may be.

It felt like I was the only one who cared about the climate and the ecological crisis. My parents didn’t care about it, my classmates didn’t care about it, my relatives didn’t care about this. I mean nobody I knew cared about this and I felt like I was the only one.

History teaches that war begins when governments believe the price of aggression is cheap.

War grows out of the desire of the individual to gain advantage at the expense of his fellow man.

Peace is not the absence of war, but a virtue based on strength of character.

I think my message to the politicians who have within their power the ability to make change is, ‚Do you really, really not care about the future of your great-grandchildren? Because if we let the world continue to be destroyed the way we are now, what’s the world going to be like for your great-grandchildren?‘

The only excuse for war is that we may live in peace unharmed.

War is not merely a political act but a real political instrument, a continuation of political intercourse, a carrying out of the same by other means.

The earth is bountiful, and where her bounty fails, nitrogen drawn from the air will refertilize her womb. I developed a process for this purpose in 1900. It was perfected fourteen years later under the stress of war by German chemists.

As I’m traveling around, I meet many small children. And when I look at a small and think how we’ve harmed this beautiful planet since I was that age, I feel a kind of desperation, anger, shame. I don’t know what I feel; I just don’t know what the emotion is.

I understand how every healthy child, every new road, puts a country on a better path, but instability and war will arise from time to time, and I’m not an expert on how you get out of those things.

The only defensible war is a war of defense.

A war with Pakistan would be an utter disaster.

Let us recollect that peace or war will not always be left to our option; that however moderate or unambitious we may be, we cannot count upon the moderation, or hope to extinguish the ambition of others.

It is fatal to enter any war without the will to win it.

The public is strongly in favor of the Kyoto Protocols, so strongly in favor that a majority of Bush voters thought that he was in favor of it. They are simply unaware.

When people speak to you about a preventive war, you tell them to go and fight it. After my experience, I have come to hate war.

Each nation feels superior to other nations. That breeds patriotism – and wars.

I do not believe that civilization will be wiped out in a war fought with the atomic bomb. Perhaps two-thirds of the people of the earth will be killed.

If burning fossil fuels was so bad that it threatened our very existence, how could we just continue like before? Why were there no restrictions? Why wasn’t it made illegal? To me, that did not add up.

People tell me that they are so hopeful when they see me and other children ‚school-striking,‘ and they say, ‚Oh the children are going to save us.‘ But no, we aren’t. We are too young to be able to do that. We don’t have time to wait for us to grow up and fix this in the future.

I talk to fashion designers and say I want some money to save the rainforest, and they say, ‚Oh, I agree with you completely Vivienne. Yes, climate change, it’s definitely happening,‘ but they don’t feel that they can do anything about it; they don’t even think ‚Well let’s stop it!‘

War contains so much folly, as well as wickedness, that much is to be hoped from the progress of reason.

It isn’t pollution that’s harming the environment. It’s the impurities in our air and water that are doing it.

Indians walk softly and hurt the landscape hardly more than the birds and squirrels, and their brush and bark huts last hardly longer than those of wood rats, while their more enduring monuments, excepting those wrought on the forests by the fires they made to improve their hunting grounds, vanish in a few centuries.

In time of war the laws are silent.

Germany has reduced savagery to a science, and this great war for the victorious peace of justice must go on until the German cancer is cut clean out of the world body.

We cannot be both the world’s leading champion of peace and the world’s leading supplier of the weapons of war.

We need every person on Earth to acknowledge that climate change is real and encourage each other and our leaders to address the challenge.

Gujarat is the fourth state in the world where we have a separate climate-change department.

The political object is the goal, war is the means of reaching it, and the means can never be considered in isolation from their purposes.

Organized murder is war, and though we demonstrate against a particular war, the nuclear, or any other kind of war, we have never demonstrated against war.

Anyone who thinks must think of the next war as they would of suicide.

Unconditional war can no longer lead to unconditional victory. It can no longer serve to settle disputes… can no longer be of concern to great powers alone.

My first wish is to see this plague of mankind, war, banished from the earth.

In war there is no substitute for victory.

There is no glory in battle worth the blood it costs.

A lot has happened over the years. And while this nation has been tested by war, and it’s been tested by recession and all manner of challenges – I stand before you again tonight, after almost two terms as your president, to tell you I am more optimistic about the future of America than ever before.

War is what happens when language fails.

The shift to a cleaner energy economy wont happen overnight, and it will require tough choices along the way. But the debate is settled. Climate change is a fact.
