Thunberg: "I see the world in black and white, and I don't like compromising."

Thunberg: "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."

Thunberg: "I believe that one person can make a difference."

Thunberg: "People are unaware of what is going on. When I talk to people, they know the basics, they know the planet is warming because of greenhouse gases... but they don't know the actual consequence of that."

Thunberg: "We can no longer save the world by playing by the rules."

Thunberg: "There are thousands of ways to take action. For example, plant trees, pick up litter, join an organisation or movement that makes a difference and especially try to influence adults and put pressure on people in power."

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

Thunberg: "I have Asperger's, I'm on the autism spectrum, so I don't really care about social codes. It makes you think differently."

Thunberg: "We all have a choice. We can create transformational action that will safeguard the living conditions for future generations. Or we can continue with our business as usual and fail."

Thunberg: "You can rebel in different ways. Civil disobedience is rebelling. As long as it's peaceful, of course."

Thunberg: "We should no longer measure our wealth and success in the graph that shows economic growth, but in the curve that shows the emissions of greenhouse gases."

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