You don't know how to fix the holes in our ozone layer. You don't know how to bring salmon back up a dead stream. You don't know how to bring back an animal now extinct. And you can't bring back forests that once grew where there is now desert. If you don't know how to fix it, please stop breaking it!
In my life, I have dreamt of seeing the great herds of wild animals, jungles and rainforests full of birds and butterflies, but now I wonder if they will even exist for my children to see.
Real environmental change depends on us. We can't wait for our leaders. We have to focus on what our own responsibilities are and how we can make the change happen.
I am afraid to go out in the sun now because of the holes in our ozone, I am afraid to breathe the air because I don't know what chemicals are in it.
Reducing our personal impact on the Earth via our ecological footprint, stop driving cars, eat less meat, all these things matter.
We find ourselves heading fully into an era of mass extinction.
Clean air and clean ocean, you can't translate that into money if you look at the cost to health, cost to fishery industry.
I don't want to be involved with just the environment because I think other issues tie so much into the environment, like native issues, children's issues, women's rights - I think they all completely tie into each other, even the economy.
Growing up there was always a sense of 'We have so many gifts and we have to use that for the betterment of the planet.'
When you are little, it's not hard to believe you can change the world.
I really have a passion for the sea, so I think it's important that whatever I do, I want to be near the sea.
The Haida people taught me when you are depleted, go to places that are sacred for you - the ocean, or a forest. That is where you will find incredible energy.
I was at Earth Summit in Rio 20 years ago... I was only 12 years old. And when I was speaking to the U.N. I was fighting for my future.
In school you teach us not to fight with others, to work things out, to respect others, to clean up our mess, not to hurt other creatures, to share, not be greedy. Then why do you go out and do the things you tell us not to do? You grownups say you love us, but I challenge you, please, to make your actions reflect your words.
I feel angry that I have been born into a society where, by no choice of my own, by no agreement, by no actual decision, I am inherently complicit in the destruction of the world. It is hard to do the right thing. You have to be militant. You have to be an activist. You have to be branded as green to do the right thing.
Well, I think it's pretty incredible watching Greta Thunberg in action.
The '90s came, and then the 2000s, and we saw radical corporate interest extremism, we've seen the disparity between rich and poor just get bigger, with globalisation and the corporate agenda on the rise ever since.
When we look as a society, we've really lost the connection between our actions and the future.
I began to lead two lives... one being a kid and the other starting to speak internationally about the environment... and advocating for social and environmental justice.
When I became a mother, I was trying so hard, using reusable diapers, washing them, looking for organic supplies even though it's much more expensive, and facing so many challenges attempting to do the right thing.
