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.

Evolution can go to hell as far as I am concerned. What a mistake we are. We have mortally wounded this sweet life-supporting planet – the only one in the whole Milky Way – with a century of transportation whoopee.

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!‘

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.

People are going to buy cheap fertilizer so they can grow enough crops to feed themselves, which will be increasingly difficult with climate change.

The reason we should do a carbon tax is because it’s the right thing to do. It’s economics 101, elementary stuff.

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

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.

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

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

It is hard sometimes to always be at the centre of attention, but when you talk about me you also have to talk about the climate.

I have a company, and I’ve got to think about that. I’m trying to do my best there, and that’s a much harder task. We recycle as much as possible, and we conserve. But I’ve always been one to save everything – I even walk up stairs on the very inside or the very outside to not wear out the tread.

I remember when I was younger, and in school, our teachers showed us films of plastic in the ocean, starving polar bears and so on. I cried through all the movies. My classmates were concerned when they watched the film, but when it stopped, they started thinking about other things. I couldn’t do that. Those pictures were stuck in my head.

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.

When we have peace, then we have a chance to save the planet. But if we are not united in peace, if we do not practice mindful consumption, we cannot save our planet.

The main message of Climate Revolution is that climate change is caused by the rotten financial system we’ve got, designed to create poverty and rip off any profits for a small amount of rich people. Meanwhile, it destroys the earth.

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.

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.

To shake your rump is to be environmentally aware.

For way too long the politicians and people in power have got away with not doing anything at all to fight the climate crisis and ecological crisis.

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

The thing that’s made me open my eyes to what was happening to the environment and climate was films and documentaries.

Would you bet your paycheck on a weather forecast for tomorrow? If not, then why should this country bet billions on global warming predictions that have even less foundation?

‚Bellyache‘ is totally fictional. I like writing about things that aren’t real. The song is about not trusting anyone and then putting trust in yourself and realizing that you don’t know what you are doing, either. Or realizing that things you do with a group of people that you think are cool in the moment are ultimately all on you.

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.

We must reject the idea that every time a law’s broken, society is guilty rather than the lawbreaker. It is time to restore the American precept that each individual is accountable for his actions.

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.

Learning about climate change triggered my depression in the first place. But it was also what got me out of my depression, because there were things I could do to improve the situation. I don’t have time to be depressed anymore.

At Virgin, we have always backed the power of the entrepreneur and inventor to find solutions to tricky problems. Why should climate change and the battle against carbon be any different?

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

Solving the climate crisis is the greatest and most complex challenge that homo sapiens have ever faced. The main solution, however, is so simple that even a small child can understand it. We have to stop our emissions of greenhouse gases.

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

When I was 11 I became very depressed. It had a lot to do with the climate and ecological crisis. I thought everything was just so wrong and nothing was happening and there’s no point in anything.

Some people say that the climate crisis is something that we will have created, but that is not true, because if everyone is guilty then no one is to blame. And someone is to blame.

Nothing is being done to stop the climate and ecological emergency from happening and to secure the future wellbeing for future generations.

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

The symbolism of the climate strike is that if you adults don’t give a damn about my future, I won’t either.

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?‘

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.

Sweden is not a green paradise, it has one of the biggest carbon footprints.

I have always held firmly to the thought that each one of us can do a little to bring some portion of misery to an end.

I’m a radical environmentalist; I think the sooner we asphyxiate in our own filth, the better. The world will do better without us. Maybe some fuzzy animals will go with us, but there’ll be plenty of other animals, and they’ll be back.

Even if producing CO2 was good for the environment, given that we’re going to run out of hydrocarbons, we need to find some sustainable means of operating.

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

First, how do we give everyone a fair shot at opportunity and security in this new economy? Second, how do we make technology work for us, and not against us – especially when it comes to solving urgent challenges like climate change? Third, how do we keep America safe and lead the world without becoming its policeman?

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.

If you can’t eat it, shoot it, or wear it, don’t bring it.

I threw my cup away when I saw a child drinking from his hands at the trough.

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.

I thought my life was mapped out. Research, living in the forest, teaching and writing. But in ’86 I went to a conference and realised the chimpanzees were disappearing. I had worldwide recognition and a gift of communication. I had to use them.

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

We can’t just continue living as if there was no tomorrow, because there is a tomorrow.

We could have saved the Earth but we were too damned cheap.

This is the moment when we must come together to save this planet. Let us resolve that we will not leave our children a world where the oceans rise and famine spreads and terrible storms devastate our lands.

I’ve grown accustomed to hotels and drastic climate change.

As you heat the planet up, it’s just like boiling a pot.

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.

At first when I heard about climate change, I was a climate denier. I didn’t think it was happening. Because if there really was an existential crisis like that, that would threaten our civilisation, we wouldn’t be focusing on anything else. That would be our first priority. So I didn’t understand how that added up.

I want the politicians to prioritise the climate question, focus on the climate and treat it like a crisis.

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.

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