Now, we put out a lot of carbon dioxide every year, over 26 billion tons. For each American, it’s about 20 tons. For people in poor countries, it’s less than one ton. It’s an average of about five tons for everyone on the planet. And, somehow, we have to make changes that will bring that down to zero.

I have been on the road and visited numerous places and met people from all over the globe. I can say that it looks nearly the same everywhere I have been: The climate crisis is ignored by people in charge, despite the science being crystal clear.

What is the use of a house if you haven’t got a tolerable planet to put it on?

Some scientists believe climate change is the cause of unprecedented melting of the North Pole, and that effects these very uncertain weather patterns. I think we should listen to those scientists and experts.

I don’t fly because of the enormous climate impact of aviation per person.

There aren’t many things that are universally cool, and it’s cool not to litter. I’d never do it.

What is a farm but a mute gospel?

Climate change is a terrible problem, and it absolutely needs to be solved. It deserves to be a huge priority.

Our economic system, run for profit and waste and based primarily on the extractive industries, is the cause of climate change. We have wasted the earth’s treasure and we can no longer exploit it cheaply.

While some doubted that connecting the world was actually important, we were building. While others doubted that this would be sustainable, you were forming lasting connections. We just cared more about connecting the world than anyone else. And we still do today.

The squandering of oil and gas is associated with one of the greatest tragedies, not in the least resolved, which is suffered by humankind: climate change.

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.

Two out of every five people on Earth today owe their lives to the higher crop outputs that fertilizer has made possible.

I’m glad to see that BMW is bringing an electric car to market. That’s cool.

If future generations are to remember us more with gratitude than sorrow, we must achieve more than just the miracles of technology. We must also leave them a glimpse of the world as it was created, not just as it looked when we got through with it.

The main message we want to get out there is that climate change is caused by the rotten economic system.

I was born in London in England in 1934. I went through, as a child, the horrors of World War II, through a time when food was rationed and we learned to be very careful, and we never had more to eat than what we needed to eat. There was no waste. Everything was used.

It is good to realize that if love and peace can prevail on earth, and if we can teach our children to honor nature’s gifts, the joys and beauties of the outdoors will be here forever.

Innovations that are guided by smallholder farmers, adapted to local circumstances, and sustainable for the economy and environment will be necessary to ensure food security in the future.

We will have to leave this planet, and we’re going to leave it, and it’s going to make this planet better.

A company shouldn’t get addicted to being shiny, because shiny doesn’t last.

I think California has the best energy.

I really wonder what gives us the right to wreck this poor planet of ours.

To shake your rump is to be environmentally aware.

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

The climate crisis is both the easiest and the hardest issue we have ever faced. The easiest because we know what we must do. We must stop the emissions of greenhouse gases. The hardest because our current economics are still totally dependent on burning fossil fuels, and thereby destroying ecosystems in order to create everlasting economic growth.

We are living in the beginning of a mass extinction and our climate is breaking down.

We shouldn’t be saying ‚Save the planet‘; we should be saying: ‚Save viable conditions in which people can live.‘ That’s what we’re dealing with here.

When the well is dry, they know the worth of water.

The effects of climate change are real and must be acted on.

In 1961, the United States began chemical warfare in Vietnam, South Vietnam, chemical warfare to destroy crops and livestock. That went on for seven years. The level of poison – they used the most extreme carcinogen known: dioxin. And this went on for years.

We have got to change our ethics and our financial system and our whole way of understanding the world. It has to be a world in which people live rather than die; a sustainable world. It could be great.

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.

The universal utilization of water power and its long-distance transmission will supply every household with cheap power and will dispense with the necessity of burning fuel. The struggle for existence being lessened, there should be development along ideal rather than material lines.

The extraction of oil, coal and minerals brought, and still brings, a cost to the environment.

If anyone has a vested interest in space solar power, it would have to be me.

I have seen firsthand that agricultural science has enormous potential to increase the yields of small farmers and lift them out of hunger and poverty.

At places like Davos, people like to tell success stories. But their financial success has come with an unthinkable price tag. And on climate change, we have to acknowledge we have failed.

I think there are more politicians in favor of electric cars than against. There are still some that are against, and I think the reasoning for that varies depending on the person, but in some cases, they just don’t believe in climate change – they think oil will last forever.

You should be attacking the carbon emissions, period, and whether it’s cap-and-trade or carbon tax or whatever, that’s the realm in which we should be playing.

I resigned from the Marine Corps and flying in 1974, even though I loved them both. I quit because I no longer wanted to fight for peace. Instead, I believe we can build a more sustainable peace by working for prosperity.

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!‘

The environment is everything that isn’t me.

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.

You could warm Mars up, over time, with greenhouse gases.

Economy forced me to become a vegetarian, but I finally starting liking it.

There must be a reason why some people can afford to live well. They must have worked for it. I only feel angry when I see waste. When I see people throwing away things that we could use.

To make a prairie it takes a clover and one bee, One clover, and a bee, And revery. The revery alone will do, If bees are few.

There’s 20 companies that I have investments in – some batteries, some solar-thermal, one big nuclear thing. We need hundreds and hundreds of companies like that, so that in a 20-year time frame we really are starting to change the energy infrastructure.

All the waste in a year from a nuclear power plant can be stored under a desk.

I am not deeply involved in Australian politics but I know there are prime ministers, governments around the world who are not acting responsibly in relation to climate change.

Many people say that this is not an easy issue, we cannot just say that this is how it is, it’s not black and white. But I say that this is black and white. Either we stop the emissions or we don’t. There are no gray areas when it comes to survival.

The threat to the planet is us. It’s actually not a threat to the planet – it’s a threat to us.

Most emissions aren’t caused by individuals, they’re caused by corporations and states.

We can’t drive our SUVs and eat as much as we want and keep our homes on 72 degrees at all times… and then just expect that other countries are going to say OK. That’s not leadership. That’s not going to happen.

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.

A diplomatic solution that puts significant and verifiable constraints on Iran’s nuclear program represents the best and most sustainable chance to ensure that America, Israel, the entire Middle East will never be menaced by a nuclear-armed Iran.

I’m frugal. I’m not a very acquisitive woman. I never waste food. If you prepare your own food, you engage with the world, it tastes alive. It tastes good.

In energy, you have to plan and do research way in advance, sometimes decades in advance to get a new system that’s safer, doesn’t require us to go around the world to get all our oil.

In the case of the environment, there’s no one to bail it out.

Even if the economy crashes, we will still burn oil.
