Actress Jerry Hall has joined the ranks of celebrity protestors who oppose runway expansion at Heathrow airport.
Ms Hall, the former wife of Rolling Stone Mick Jagger, joined a group of mothers and their children at a climate change rally outside Parliament.
Some of the children were dressed up as animals that organisers say are at risk of extinction caused by climate change.
In January, the government approved a controversial plan to add a third runway at the west London airport.
The move will lead to the razing of the village of Sipson and the protest included children who attend the village primary school.
Ms Hall said: "Climate change is the biggest threat the world has ever known and it is happening right in front of our eyes.
"All the experts say governments need to act now if we're going to have any chance of saving our children from catastrophe."
Ms Hall joins other celebrities such as Emma Thompson and Alistair McGowan who have opposed airport expansion.
The Parliament protest was organised by campaign group We Can, founded by a group of mothers including Rosie Boycott, who are concerned the government is not taking concerted action to tackle climate change.
Co-founder Jennifer Ruhemann said: "We've got a government that says it wants to cut carbon emissions and yet it is building more airports and planning more coal-fired power stations."
The government has stressed that expansion will come with strict pollution controls and noise limits.
