Dame Vivienne Westwood, the international fashion designer, has spoken on the steps of St Paul's Cathedral about her fear of climate change and the lack of culture in today's society.
Addressing the Occupy London camp, whose members have been pitched outside the cathedral since October, Dame Vivienne said: "What you're doing, I think it's wonderful."
She added: "I've got to jump on to my hobby horse. I'm terrified by the problem of climate change. Climate change is connected completely to the financial situation.
"We have nothing else cheap left to exploit.
"We are completely in danger from lack of culture. We were all trained up to be consumers in the twentieth century: throw away the past, the future will take care of itself, catch the latest thing and suck it up. We don't have any art today."
She urged the campaigners to visit the National Gallery and the British Museum, because, she said: "An art lover is a freedom fighter."
Speaking afterwards, Dame Vivienne said of the Occupy camp: "I'm so pleased for what they're doing. I think it's just great and I think all young people should start doing more of this."
Dame Vivienne added: "I think all we can hope for is public opinion, that's the only thing that will save us.
"We're supposed to be in a democracy but unless people start actually behaving as if they are, we don't have any chance. People always think somebody else will do it for them."
