When I first saw a picture of the crucifixion, I lost respect for my parents. I suddenly realised that this is what the adult world is like - full of cruelty and hypocrisy.

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.

Nothing is costed properly and it's destroying the earth. We need to re-educate people that what is good for the planet is good for the financial system.

I've always felt heroic about my life... As a child, I remember little girls in the playground moaning about how boys could do more than they could. I didn't think that was the case at all. My parents didn't treat me as a girl.

It's true the punk fashion itself was iconographic: rips and dirt, safety pins, zips, slogans, and hairstyles. These motifs were so iconic in themselves - motifs of rebellion.

I think it is terribly important to have opinions, and to think. We live in a world of action without thought.

Buy less, choose well, make it last. Quality rather than quantity: That is true sustainability. If people only bought beautiful things rather than rubbish, we wouldn't have climate change!
