The 50-year-old star is a vocal campaigner on green issues, having last year (15) fronted a campaign to turn large parts of her homeland into a protected wildlife area. In 2013 she also made a documentary with famed British naturalist David Attenborough.

And in an interview with Guardian Australia, the It's Oh So Quiet singer revealed she is so concerned about climate change she wants politicians to take drastic action to reduce the levels of carbon dioxide in the atmosphere.

"Everybody wants to save the planet," she says. "By now the dinosaur conservatives are in a minority, but overall people don't know where to start. The biggest hurdle is the functionality of it.

"What should happen now is the government says: 'OK, we are in an emergency now and everyone has to walk everywhere.' There will be no cars - a whole list of things. The way we switch to the new way of living has to be so drastic."

The star draws a comparison with U.K. government officials' actions to improve air quality in cities in the 1950s. After London experienced severe air pollution in 1952, British lawmakers passed a number of laws banning certain fuels and offering incentives to people for no longer using coal to heat heir homes.

"It's like with the coal in London, because people couldn't breathe," she explains. "When it was banned, things actually did change but change came from above. Something like that has to happen."

On her love of the natural world, the musician adds, "I am more used to being in nature. I feel normal. In cities I feel like I am holding my breath. I feel claustrophobic, like I am living in an airport."

In November last year Bjork joined music stars including Blur frontman Damon Albarn, Coldplay, Iggy Pop and the late David Bowie in signing a letter pleading with politicians to take measures to agree upon action to prevent climate change at a conference in Paris, France.
