Not having hope is not an excuse for not doing something.

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.

My message is that if we do not care about the climate crisis and if we do not act now then almost no other question is going to matter in the future.

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.

People are underestimating the force of angry kids.

It is our future on the line, and we must at least have a say in it.

My message to the Americans is the same as to everyone - that is to unite behind the science and to act on the science.

Even if the politics needed doesn't exist today, we still need to use our voices to make sure that the people in power are focused on the right things. Because this is a democracy, and in a democracy, people are the ones who run the country.

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

I really miss having a routine because now I've been on the road constantly for several months. I like routines, so it would be nice to get those routines back.

My message to all the activists is to just keep going, and I know it really may seem impossible and hopeless sometimes - it always does - so you just have to keep going because if you try hard enough and long enough you will make a difference.

It's empowering to know I am doing something, I am taking a stand, I am disrupting.

We are not going to be satisfied by politicians saying 'we support you' and then walking away. We won't be satisfied until they meet our demands and act. That's why simply taking a selfie or posting support on Twitter isn't enough. That's why we have to keep striking.

I feel strange when I get applauded by people in power... because it's obvious that it's them I'm criticizing, but they can't show that in front of the cameras. It's quite funny sometimes.

There's always going to be people who don't understand or accept the united science, and I will just ignore them, as I'm only acting and communicating on the science.

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

The best thing about my protest has been to see how more and more people have been coming and getting involved.

I believe that one person can make a difference.

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

When I have been travelling around to speak in different countries, I am always offered help to write about the specific climate policies in specific countries. But that is not really necessary. Because the basic problem is the same everywhere.

Some say we should not engage in activism. Instead we should leave everything to our politicians and just vote for a change instead. But what do we do when there is no political will? What do we do when the politics needed are nowhere in sight?

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.

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

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.

I don't easily fall for lies, I can see through things.

I personally have stopped flying. I have stopped eating meat and dairy.

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 don't really like being in the centre of attention.

I'm very weak in a sense. I'm very tiny and I am very emotional, and that is not something people usually associate with strength.

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

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

I don't think I would be interested in the climate at all if I had been like everyone else.

Being young is a great advantage, since we see the world from a new perspective and we are not afraid to make radical changes.

When I was maybe eight or nine years old, I first learned about the climate crisis in school. My teachers taught me about it and we saw films and pictures of plastic in the ocean and extreme weather events. Those pictures were just stuck in my head; I thought, there is no point in anything.

So when I speak in front of thousands, tens of thousands of people, I don't really get nervous because I know what I want to say and I know what message I want to give.

I just know what is right and I want to do what is right.

I think that once you fully understand the climate and ecological emergencies, then you know what you can do as well. And, of course, there's a lot of things you can do in your everyday life, but we cannot be focusing on these individual things you can do. We have to see the full picture.

I'm not saying that people should stop flying. I'm just saying it needs to be easier to be climate neutral.

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.

Life is short, and if we enjoy every moment of every day, then we will be happy no matter what happens or what changes along the way.

I'm so grateful for all the experiences I've had; the life lessons I've learned along the way are just completely invaluable.

I've learned that you have to make careful choices because everything has an impact. I've also learned that you can't please everyone in life, so please yourself and figure out what really matters.

I learned a few years ago that balance is the key to a happy and successful life, and a huge part of achieving that balance is to instill rituals into your everyday life - a nutritious balanced diet, daily exercise, time for yourself through meditation, reading, journaling, yoga, daily reflection, and setting goals.

I typically have breakfast, have a snack, have lunch, have a snack, and have dinner.

Your money is power, so be aware of the products you're buying and the companies you're supporting to make sure you're helping the companies that are leading the way in sustainability.

As long you are doing what you love and making decisions from the heart, you will be successful.

I think whenever you have any kind of injury or challenge, you just have to deal with it the best you can. You have to decide what's important to you and focus on getting back to where you want to be. And enjoy where you are and what your goals and dreams are and just give it 100 percent.

I've had cumulative concussions and realized that's something you carry with you.

When you choose to take the road less traveled, it can sometimes be a bumpy ride along the way, but if you're doing it for the right reasons, then the reward is so great.

Mt. Hood is still one of my favorites for its sun, warmth, and slushy, forgiving conditions.
